Ancient Egyptian Math

Introduction to Ancient Egyptian Math:
       In ancient Egyptian math was probably the first civilization to observe the scientific arts. The ancient Egyptian math was talented in medicine and applied math. But there is huge bodies of papyrus literature describe their achievements in medicine, no records of how they reached their mathematical conclusions. The advance grasping power of the subjects since their exploits in astronomy and administration would not have been possible without it. Let us see about ancient Egyptian math.

Decimal System in Ancient Egyptian Math :



  • 1 - represented by a single stroke.
  • 10 - represented by a drawing of a hobble for cattle.
  • 100 - represented by a coil of rope.
  • 1,000- represented by a lotus plant.
  • 10,000- represented by a finger.
  • 100,000- represented by a tadpole or frog.
  • 1,000,000- represented by the following figure of a god with arms raised above his head

For example:         

Numeral Hieroglyphs in Ancient Egyptian Math:

  • Hieroglyphs are developed in 3200 BC and carved in stone.
  • There are 7 Symbols.
     
  • For example 5120 is written as: 
  • The highest value number is written to the left of the minor number.
  • Where there is above one row of numbers reading starts at the top.
Hieroglyphic signs are divided into four categories:
                                 
  • Alphabetic signs are represented a single sound. An ancient Egyptian math took most vowels for determined and did not represent such as 'e' or 'v'.
  • Syllabic signs are represented by a combination of 2 or 3 consonants.
  • They are followed by an upright stroke, to indicate that the word is complete in one sign.
  • A picture of an object are helps the reader. For example; if a word expressed an abstract idea, a picture of a roll of papyrus tied up and sealed was included to show that the meaning of the word could be expressed in writing although not pictorially.
