                                Module 1 in HISTORY OF MATHEMATICS
                                    EGYPTIAN MATHEMATICS
    EGYPTIAN MATHEMATICS
            The earliest Egyptian settlements that
    were located along the Nile date back to 6000
    BCE. The use of mathematical practices in
    Ancient Egypt was tightly connected with
    religion and agriculture. The Egyptians were
    known to record the seasons and describe the
    patterns of moon phases.
    System of measurement
            At the dawn of their civilization, the
    Egyptians developed a unique system of
    measurement. It was only natural that the ancient
    units of measurement were based on body parts as
    the easiest way to find the size of an object is to
    compare it with the length of various parts of the
    body. Let’s explore some units of length for a
    better understanding of the system:
   The finger, the basic unit, was about 1.875 cm
   Four fingers constituted the palm that was
    approximately 7.5 cm
   Seven palms constituted the cubit that was about 52.5 cm
    Symbols
           God heh or a man with both hands raised was the symbol for a million, sometimes used for infinity
    also. A symbol resembling a circle was again used to represent infinity because a journey through a circle
    never ends.
    Multiples of these values were expressed by repeating the symbol as many times as needed. As they did not
    have a concept of zero, there was no symbol for it.
    Numerals
           According to scientific evidence, the Egyptians were the first to develop the base 10 numeration
    system. Again, using body parts, they created a relatively simple system that was based on ten figures.
Archeologists believe that the Egyptians invented the decimal numeric system around 3000 - 2700 BCE. The
Egyptians used the following hieroglyphs to represent numerals:
                                   ANCIENT EGYPTIANS NUMERAL SYSTEM
      A stroke was used for units – one stroke meant “one,” two strokes stood for “two,” etc.
      An arch was used for tens – one arch was used for “ten,” two arches represented “twenty,” etc.
      A coiled rope was used for hundreds – one coiled rope meant “100,” while three coiled ropes were
       used to represent “three hundred,” etc.
      A lotus plant was used for thousands – one flower denoted “1,000,” four flowers meant “4,000,” etc.
      The number 10,000 was depicted by a finger
      A frog was used to depict the number 100,000
      A hieroglyph depicting a kneeled god with raised arms denoted 1,000,000.
Fractions
        The development of trade led to the appearance of fractions. According to archeological evidence, the
ancient Egyptians introduced fractions as early as 1000 BCE. The reciprocal of a fraction was depicted by the
hieroglyph “mouth.” Besides, they had special hieroglyphs to write such fractions as 1/2, 2/3, and 3/4. The
use of fractions helped them to find the approximate area of a circle – they noticed that the area of a circle that
has a diameter of 9 units is equivalent to the area a square of side 8 units. Therefore, to find areas of other
circles they multiplied their diameter by 8/9 and then squared it. Thus, the ancient Egyptians obtained the
approximate value of p.
ACTIVITY 1
Direction: Convert the following Egyptians hieroglyphics into modern day numbers.
                                                                                                                 2
ACTIVITY 2
Direction: Add or subtract the given Egyptians Hieroglyphics.
THE AHMES PAPYRUS
The Ahmes was written in hieratic, and probably originated from the Middle Kingdom: 2000-1800 BC. It
claims to be a ``thorough study of all things, insight into all that exists, knowledge of all obscure secrets." In
fact, it is somewhat less. It is a collection of exercises, substantially rhetorical in form, designed primarily
for students of mathematics. Included are exercises in
      fractions
      notation
      arithmetic
      algebra
      geometry
      mensuration
THE RHIND PAPYRUS
        The Rhind Papyrus, dating from around 1650 BCE,
is a kind of instruction manual in arithmetic and geometry,
and it gives us explicit demonstrations of how
multiplication and division was carried out at that time. It
also contains evidence of other mathematical knowledge,
including unit fractions, composite and prime numbers,
arithmetic, geometric and harmonic means, and how to
solve first order linear equations as well as arithmetic and
geometric series. The Berlin Papyrus, which dates from
around 1300 BCE, shows that ancient Egyptians could
solve second-order algebraic (quadratic) equations.
                                                                                                                 3
          Practical problems of trade and the market led to the development of a notation for fractions. The
papyri which have come down to us demonstrate the use of unit fractions based on the symbol of the Eye of
Horus, where each part of the eye represented a different fraction, each half of the previous one (i.e. half,
quarter, eighth, sixteenth, thirty-second, sixty-fourth), so that the total was one-sixty-fourth short of a whole,
the first known example of a geometric
series.
          Unit fractions could also be used
for simple division sums. For example, if
they needed to divide 3 loaves among 5
people, they would first divide two of the
loaves into thirds and the third loaf into
fifths, then they would divide the left over
third from the second loaf into five pieces.
Thus, each person would receive one-third
plus one-fifth plus one-fifteenth (which
totals three-fifths, as we would expect).                    Ancient Egyptian method of division
MOSCOW PAPYRUS
        The Moscow Papyrus is one of the oldest written mathematical texts from
ancient Egypt around 2000 B.C to 1800 B.C. The Moscow Papyrus contains 25
mathematical problems. Some of the problems are unreadable or too damaged to
translate. Problem 14 from the Moscow Papyrus shows an illustration with an example
to find the volume of a truncated pyramid. The modern formula for a similar figure,
called frustum, is V= (a^2 + a*b + B^2)*(h/3), where a,b, and h are shown in the
diagram below.
                                                      The text is now located in the largest museum in Europe,
                                                 the Pushkin Museum of Fine Arts in Russia. This ancient piece
                                                 of mathematical history inspires awe and wonder in those
                                                 appreciative of mathematics because the Egyptians never
                                                 explained “how” their example in problem 14 worked, nor did
                                                 they show any deductive reasoning behind this problem.
        Finding the volume of a truncated pyramid is very challenging if doing so by experiments alone. One
cannot just stumble to this conclusion just by trial and error. No one knows how the Egyptians derived the
formula, and considering that the author of the text remains unknown, we might never know. However, many
historians of mathematics have their theories, but even their theories are imminent. Mathematical historians
have little to no evidence to prove their theories, since the text was written over 4000 years ago.
                                                                                                                4
       Amazingly, considering the age of the Moscow Papyrus, it is still being carefully examine by
Egyptologists. This is a valuable piece of history and is worthy of being recognized in a great museum like
the Pushkin Museum. One can only wonder of the brilliance or good fortune of the Egyptians.
