It is believed that the Babylonian sexagesimal system has carried over into today's society. It is evident in the fact that it is still used when measuring time and angles in minutes and seconds. The lack of a zero created complications. Therefore the Babylonians eventually created a new symbol to represent an empty place value. The symbol is the wedge shape tilted to the side a bit.
Babylonian arithmetic is a well-developed rhetorical algebra.
The solution of a problem was written as a prose argument. The Babylonians might have treated addition as we treat it today. They might have grouped the numerals in each column and shifted columns if possible. There is proof that the Babylonians were solving quadratic equations. They would solve them either by substitution into a general formula or by completing the square .
