# Ancient Egyptian Mathematics In The Early Dynastic Period History Essay

Quantification in the early dynastic period and the old land was done utilizing different methods of computations and with clip these methods were developed to go the mathematics that we use today. The Ancient Egyptians were besides involved in covering with different computations and some of those developed by the bookmans are still being used in the recent mathematics.

The most prehistoric usage of mathematics was in numbering particularly in the stock lists of ownerships, captives and or merchandises. The mid graduated table and little measurings of length, land countries and volumes of the solid stuffs were developed out of the breadths or lengths of parts of the organic structure. Examples of these are cubit arm lengths, manus spans, breadths of thenars and fingers. Dry grain and liquid steps originated from the usage of vass like cups, jugs, pokes, silos. The development of additive measuring of long distances could hold occurred due to the ancient numeration of gaits and the bluffly timed boat motions. The constitution of conventional steps of clip in footings of hours, yearss, months, and old ages occurred due to numbering of the repetitive natural phenomena including the visible radiation of the twenty-four hours, darkness of the dark, solar, lunar and the heavenly rises, scenes and their apogees[ 1 ].

The alteration of the additive measuring in edifice and surveying gave rise to scaled regulations of dual cubit rods for the short steps and the rope lengths for the longer steps in order to function the land surveyors and builders. Herodotus pointed out that the demand to mensurate the Egyptian land after the implosion therapy by Nile River led to development of practical geometry in land measuring. Hieroglyphic Numberss were rampant in Early Egyptian Annalss on the rock[ 2 ].

Civilization in Egypt was reached at a really early period due to the Nile River and a good clime. By 3000 BC, two of the earlier states united to organize a exclusive Egyptian state under one swayer. The large country covered by this state required more complicated disposal, some system of revenue enhancements and ground forcess needed to be supported. The society continued to spread out and therefore records needed to be kept and more calculations needed to be done as the people bartered their goods. A high demand for more numeration arose and numbers together with Hagiographas were more needed in order to enter the minutess. By 3000 BC they had already introduced hieroglyphic composing which marked the start of the Old Kingdom period in which some pyramids were built. These hieroglyphs nevertheless subsequently paved manner for priestly book. This priestly authorship was for authorship and numbers. The Egyptians were practical in the attack to mathematics and besides the trade needed them to cover in fractions. They besides needed to invent all the methods of division and generation. This is because their figure system was non good matched for the arithmetical computations.

The Roman numbers are easy to understand but have no room for division and generation. These early numbers are carved on rock memorials, vases and temples though they give little cognition on any mathematical computations with figure system within ancient Egypt. Egyptians so began to utilize the planate sheets of dried papyrus reed as their documents and the tips of the reed as their pen and this helped in faster development of rapid agencies of authorship and therefore priestly numbers and composing. Two major mathematical stuffs survived particularly in the papyri epoch. These are Rhind papyrus and the Moscow papyrus with some interlingual rendition into the priestly book and it is from these two that we get so much information on Egyptian mathematics[ 3 ].

In the twenty-four hours to twenty-four hours lives of the Egyptians, mathematics was largely used by priestesses and priests who were in charge of their workers, Masons and applied scientists, tradesmans and their consumers, surveyors, revenue enhancement aggregators, and besides the cooks. The higher signifiers of mathematics were used by those who had building-related occupations and besides the priests. The remainder of the people merely used the simple mathematics that is besides used today. In 280 BC which was the most indispensable period in developing of mathematics and was referred to as the Ptolemaic Period, Euclid made great promotion in plane geometry. In 1300 BC the Berlin Mathematical papyrus was discovered and it explained more on the 2nd order algebraic equations. In the 1650 BC, the Rhind Mathematical papyrus was written and it helped to detect geometry, arithmetic series and algebraic equations. In 1800 BC, Hieratic numbers on papyrus were discovered and besides the Moscow Mathematical papyrus was written which had the expression of happening the volume of the frustum. In 2700 BC, there was the to the full developed base ten numeration system which was the earliest to be developed and there was besides the Preciseness Surveying that happened in Giza pyramids which is a singular effort of technology. In 3200 BC the Hieroglyphic book came up and the besides numbering on rocks[ 4 ].

The Rhind papyrus is named after a Scots Egyptologist Henry Rhind who bought it in Luxor in the twelvemonth 1858. The papyrus is a coil about six metres long and 1/3 of a metre broad. It was written in 1650 BC by the Scribe Ahmes who stated that he was duplicating a manuscript which was 200 old ages older. The original papyrus that the Rhind papyrus is based day of the months back to 1850 BC.

The Moscow papyrus day of the months besides from around this clip. It is presently going more widespread to mention to the Rhind papyrus after Ahmes other than Rhind because it seems fairer to call it after the Scribe himself instead than after the individual who bought it comparatively late. The Scribe who wrote Moscow papyrus did non enter his name but is frequently referred to as Golenischev papyrus merely after the individual who bought it. The Moscow papyrus is in the Museum of Fine Arts in Moscow and the Rhind papyrus is seen in the British Museum in London. The Rhind papyrus has 87 jobs whereas the Moscow papyrus has 25 jobs. These jobs are practical with an exclusion of a few and most of them operate utilizing fractions. The Rhind papyrus has so many amounts of division and an illustration is a amount of spliting n loaves among 10 work forces. These jobs of spliting the loaves reasonably were really of import in developing the Egyptian mathematics. Some of those jobs required the solutions of some equations that would be formed in the procedure of happening the reply. A good illustration is job 26 which asks for the needed measure that would be added to a one-fourth of that measure in order to give 15. Some of the other jobs involve geometric series and an illustration is job 64 which asks us to split some 10 hekats of the barley between 10 work forces such that each adult male gets 1/8 of the hekat more than the predating 1. Other jobs involve geometry and an illustration is job 50 which asks for the country of a circular field with a diameter of 9 khet.

The Egyptians were non taking Numberss as merely abstract measures but they thought of them as specific aggregation of objects. In order to get the better of lacks in the systems of their numbers, the Egyptians came up with cunning ways to accommodate generation as it is shown in Rhind papyrus[ 5 ].

The Great pyramid was built with some mathematical invariables in their heads. This is because so many writers have given the measurings of the Pyramid. The angle which is between the foundation and one of the faces is taken to be 51A° 50 ‘ 35 ” and the secant of the same is 1.61806 and this is truly close to the aureate ratio of 1.618034. They instead used the computation of taking the ratio of tallness of the aslant face to half the length of the side of the square base. The cotangent of the incline angle is close to Iˆ/4. The Egyptians nevertheless used the ratio of the sides that made this figure tantrum. There is a strong relationship between Iˆ and aureate ratio. They used the regulation of 3 4 5 trigon in this building. So many finds have been made about this pyramid utilizing mathematics. Using Egyptian cubit, the margin is about 365.24 which is the figure of yearss in a twelvemonth. Doubling this, it equals a minute of a grade on the equator. Its tallness multiplied by 10 to the power of 9 offers approximately the distance between the Sun and the Earth. Its margin divided by two so multiplied by its tallness gives pi – 3.1416. Its weight multiplied by 10 to power 15 gives approximately weight of the Earth. Adding up the cross diagonals of the base we get the figure of old ages it takes the whole Earth ‘s polar axis to return to the original starting point which is 25,286.6 old ages ( Fischler 181 ) .

These Egyptians used some ancient calendars because they needed to cognize when the Nile River would deluge. They decided that the start of the twelvemonth would be heliacal rise of Sirius which was the brightest star in their sky. This occurred in July and they took this as their start of the twelvemonth. This would state people to fix for the inundations because the Nile flooded shortly after this. The twelvemonth had 365 yearss up until the twelvemonth 2776 BC when the one-fourth was incorporated. This civil twelvemonth was subsequently divided into 12 months and some 5 twenty-four hours excess period at the terminal of every twelvemonth. This was the footing for the Gregorian and Julian calendars[ 6 ].

The Egyptians besides used Hieroglyphs which were little images that represent words. For numbers, they had a base of 10 systems of the hieroglyphs. There were separate symbols for several units in 10s like one unit, one hundred, one 10, and one 1000 up to one million. In an illustration to do 276 they needed 15 symbols: 2 “ hundred ” symbols, 7 “ 10 ” symbols, and 6 “ unit ” symbols. This illustration and another one for 4622 are seen on rock carving in Karnak and dating to 1500 BC which is now seen in Louvre in Paris. Adding up these numerical hieroglyphs was rather easy ( Marshall 100 ) .

Fractions in these times were merely limited to unit fractions which are of the signifier 1/n where N was any whole number. These were represented by puting the symbol on a oral cavity intending it was apart of the figure above it. If the figure was excessively large the portion symbol was placed merely on the first portion on the right. From this, the Egyptians advanced to priestly numbers that allowed Numberss to be written in compact signifier. Using this system, fewer symbols were used. In doing the figure 9999 it used 4 priestly symbols other than 36 hieroglyphs. They nevertheless did non organize some positional system because they could be written in a haphazard or any order. They nevertheless changed with clip such that it could be written in a consecutive order that was known throughout the part. The hieroglyphs were carved on rock whereas the priestly numbers were written on the papyrus.

Mathematicss was besides used in mensurating consecutive lines, clip, and the Nile deluging degree, numeration of hard currency, ciphering the land country, working out revenue enhancements and besides in cooking. It was besides used in mythology and in edifice of grave, architectural wonders and pyramids. The geometry of Plato, Euclid, Pythagoras and Eudoxus were studied in the Nile Valley sanctuaries. The priests during the 1832 BC had mastered most and about every procedure of arithmetic as is shown by papyri. They had besides developed some expressions which helped them to happen all the solutions of jobs with one or two terra incognitas together with “ think of a figure jobs. ” This coupled with geometric and arithmetic patterned advances shows that algebra was good developed in the Nile Valley by the twelvemonth 1832 B.C.

In the Rhind Papyrus, the Problem 56 gives equations that involve happening an angle of the incline of a pyramid ‘s face and this means the cotangent. This means that trigonometry was developed in the Nile vale. The pyramid theoretical accounts were used to obtain cosine and sine values. There is an architectural drawing which shows that Nilotic applied scientists had known how to happen the countries under curves ; this is dated back more than 5,000 old ages ago. Flinders Petrie found that the designers built most of the constructions in right trigons that followed the theorem of a2 + b2 = c2, where the two sides are represented by a and B and so degree Celsius is the hypotenuse. Pythagoras studied in those temples of Nile vale for over 20 old ages and so it is non a admiration that the theorem had Egyptian beginning ( Flischer 168 ) .

Examples of what the Egyptian schools learned include: how many loaves can be made from some certain sums of grain and the figure of bricks that could be needed to do a incline of length ten and height Y. The papyrus itself was found in ruins of the little edifice that was near Ramesseum. This is a transcript that was made by Ahmose, the Scribe, during the reign of Hyksos Pharaoh. He states that the Hagiographas were comparable to those written at the minute of Amenemhet III who reigned between 1842 B.C. and 1797 B.C.

The early Egyptians merely divided and multiplied by two. This means that if they needed to happen e ten 5, they used vitamin E x 2 + vitamin E x 2 + vitamin E whereas 13 / 4 was calculated as 4 x 2 + 4 = 12, 13 – 12 = 1, so the reply became 3 A? . In order to acquire whole Numberss like 32, they would compose: 10 + 10 + 10 + 1 + 1. This made their mathematics to be insistent and really long ( Sanford 86 -103 ) .

Richard Gillings reported that rhetorical algebra ‘s dividendo [ ( y -x ) /x = ( q -p ) /p ] and alternando [ ( y/x ) = ( q/p ) ] as the proportions that were used in incorporating natural stuffs of beer in RMP 75 and 73. This was the harmonic mean which assorted ingredients in a sacrificial staff of life in RMP 76 expression. RMP is the Rhind Mathematical Papyrus in this instance. There are four ancient paperss and Hagiographas that cover the abstract accounts of Numberss and the higher signifiers of arithmetic. These appear in the two already discussed papyri and the Akhmim Wooden Tablet and the Kahun Papyrus in the Egyptian Mathematical Leather Roll. The arithmetic scaled hekat and some other weights step units. This hekat made usage of Eye of Horus quotients. The Akhmim Wooden Tablet ( AWT ) made a list of five divisions of hekat get downing with hekat integrity that was valued at ( 64/64 ) . This hekat integrity was divisible by 3, 7, 10, 11 and 13 which were recorded utilizing the exact replies of the unit fraction. The initial half cited two quotients, ( 64/64/n ) . An illustration was when 3 was used to split ( 64/64 ) , with a losing mediate stairss giving a quotient 21/64 with a balance 1/192. He wrote the quotient 21/64 as ( 16 + 4 + 1 ) /64 giving ( 16 + 4 + 1 ) /64, or ( 1/4 + 1/16 + 1/64 ) hekat. Then the balance scaled 1/192 to ro units, 1/320 of a hekat, scaling ( 1/192 ) * ( 5/5 ) by lettering ( 5/3 ) * ( 1/320 ) and in conclusion ( 1 + 2/3 ) Ro ( Gillings 100 ) .

The Egyptians were besides familiar with square roots and roots. They plotted an arch by utilizing some beginnings that had to be measured at accustomed intervals right from the base line and from this they could acquire countries. To happen the country of circles, they used the country of a square on an 8/9 of the given diameter, or besides used ( 7/8 ) squared. The Egyptians were cognizant that the given volume of a given frustum of the square pyramid was equal to ( 1/3 ) of the tallness ( a2 + Bachelor of Arts + b2 )[ 7 ].

There were major parts of this Egyptian mathematics to what is now the modern mathematics. The denary notation of Numberss of 400 BC is used much today. The value of Pi at 3.1416 was calculated by Aryabhatiya in 528 AD. The numerical nothing and besides the negative Numberss were discovered in 628 Ad by Brahmagupta. The drifting point system in 1350 AD was founded in Kerala School of mathematics ( Parkinson 112 ) .

In decision, the basic constructs of the Egyptian Mathematicss are many and can be described depending on the part it made in the development of the mathematics as a societal scientific discipline and a topic of survey. First, the simple construct of numeration and measurement were brought up together with the primary marks which were invented in order to maintain path of the results of measurement and numeration. Second, the primary thought of entering tabular arraies of mathematics helps to do computation in signifier of tabular arraies easier and has its beginning in Egypt. The determination of quotient to factors of 2 and uneven Numberss runing from 3 to 101 has a tabular array in the antediluvian mathematics. Third, the construct of the theoretical account jobs and generalising the jobs in order to seek an unknown measure has its beginning in the ancient Egyptian mathematics and it is the inchoate measure to the generalization in the topic of mathematics.

The construct of proving in order to acquire prove of the theory in inquiry has besides its beginning in Egypt. Working backwards with the deliberate reply so as to demo that it fits the diction of the job was most practiced in the ancient Egypt. The construct of the standard computation of expressions in finding of volumes and countries in respect to rectilinear dimensions besides has its beginning in ancient Egypt. These dimensions may include trigons, circles, squares, and trapezoids, cylindrical and rectangular containers. The construct of the incline of some isosceles triangle pyramids and cone was besides practiced much in the Ancient Egypt. This helped to come up with the 3 4 5 regulation and besides the Pythagoras theorem used this primary construct. Last, the construct of quadrature which is the decrease of the curving figures to some figures that are bounded by the consecutive lines or planes has its background in Egypt.. The curving figures are either two or three dimensions. This though has been modified in Greek ( Marshall 115 ) .
