The ancient Egyptians
were possibly the first civilization to practice the scientific arts. Indeed, the word chemistry
is derived from the word Alchemy which is the ancient name for Egypt.
Where the Egyptians really excelled was in medicine and applied mathematics. But although there is a large body of papyrus literature
describing their achievements in medicine, there is no records of how they reached their mathematical conclusions. Of course they must have had an advanced understanding of the subject because their exploits in engineering, astronomy
and administration would not have been possible without it.
The Egyptians had a decimal system
using seven different symbols. 1
is shown by a single stroke. 10
is shown by a drawing of a hobble for cattle. 100
is represented by a coil of rope. 1,000
is a drawing of a lotus plant. 10,000
is represented by a finger. 100,
000 by a tadpole or frog 1,000,000
is the figure of a god with arms raised above his head.
The conventions for reading and writing numbers is quite simple; the higher number is always written in front of the lower number and where there is more than one row of numbers the reader should start at the top.
