short history of the calculator

People have been making calculators for over 2000 years. Yes, 2000 years. That's the fact. And thar's the timeline.

You can't shorten the timeline.

You have to work with what is there.

You may not have to include every detail of the last 2000 years, but you've got to get the basic changes in there.

Mesopotamian
The period 2700–2300 BC saw the first appearance of the Sumerian abacus, a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system.[11]

Some scholars point to a character from the Babylonian cuneiform which may have been derived from a representation of the abacus.[12] It is the belief of Old Babylonian[13] scholars such as Carruccio that Old Babylonians "may have used the abacus for the operations of addition and subtraction; however, this primitive device proved difficult to use for more complex calculations".[14]
