Egyptian multiplication was done by a repeated doubling of the number to be multiplied (the multiplicand), and choosing which of the doublings to add together (essentially a form of binary arithmetic), a method that links to the Old Kingdom.
How does Egyptian arithmetic work?
The Egyptians introduced a method based on successive doublings, related to the way digital computers multiply, which works because every positive whole number can be expressed as a sum of powers of 2; that is, every positive integer has a base 2 representation. 12×12=144 from Rhind mathematical papyrus, Problem 32.
Why did Egyptians use base10?
We use base 10 because we have 10 fingers. In base 10, ten digits are used and those digits are 0 through 9. The Mayans used a vigesimal (base 20) number system, the Babylonians used a sexagesimal (base 60) number system, and the Egyptians used a duo-decimal (base 12) number system.
Did the Egyptians have zero?
In ancient Egypt, the word for zero was nefer, a word whose hieroglyphic symbol is a heart with trachea. Nefer could mean “beautiful, pleasant, and good.” But it was also used to represent the base level from which temples and other buildings arose. It is from that meaning that our current concept of zero evolved.

Egyptian Fractions
Ancient Egyptians used numbers and basic calculators as early as 2700 BCE. However, they expressed fractions in a very different way to the methods we employ today. Specifically, as opposed to recording three quarters as 3/4, they opted to record the ratio as the sum total of the fractions that had a numerator of one.
The Greedy Algorithm
The most basic approach by which we can express a vulgar fraction in the form of an Egyptian fraction (i.e., the sum of the unit fractions) is to employ the greedy algorithm that was first proposed by Fibonacci in 1202.
