**Egyptian**

The ancient Egyptian were possibly the first civilisation
to practice the scientific arts. Indeed, the word chemistry is derived from
the word Alchemy which is the ancient name for Egypt.

Where the Egyptian 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 Egyptian had a decimal system using seven different
symbols.

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.
