They would always use multiplication to create reciprocal tables to aide their calculations. The Babylonians are mostly notorious for their great skill of constructing mathematical tables. We have been using the same system for over 4000 years now.

They split a full day up into 24 hours, each hour split into 60 minutes and each minute split into 60 seconds.
They basically used their base 60 system to create a full day’s time. They were the first civilization to come up with a time scale of a full day. The Babylonians also used formulas such as the Pythagorean theorem to solve lots of their problems. Like every other math, it just takes practice and repetition. I found that this numeration system is just as easy as plane addition because there are actually only two symbols you are dealing with. Remember, if any numerals are to the left of the second 60-group, then they have a value of 602. If any numbers were to the LEFT of the second 60-group, they had the value of 60 X 60 or 602. The Babylonians took their positional system to the next level. A true sexagesimal system requires 60 different symbols.
The numbers within each 60-group are written by a grouping system. This is because only the numbers larger than 60 use the position rule. Even though this system is considered a positional system, it is not entirely positional. Just remember, after the first set of numbers, all you have to do is drop in a multiplication sign, 60, and an addition sign.

Learning how to interpret Babylonian equations is like learning a new language only it’s a lot easier than it looks. For the numbers larger than 60, the symbols arrowhead and flower are written to the left of another arrowhead symbol and now make a new value that is 60 times larger than the original value. The arrowhead symbol MUST appear to the left of any flower symbols to represent numbers smaller than 60. Instead of the numbers going up to 20 before a new group of numbers, the numbers in the Babylonian system went up to 60, making this system a “Base 60” system. Much like the Mayan numeration system, the Babylonians used a base system. Since papyrus was not amongst the Babylonians, they used clay as a writing medium, making the cuneiform much less pictorial than the Egyptian system. This system is called a sexagesimal system. Unlike the Egyptian system which consisted of grouping, the Babylonian system consist of a positioned system, which was found to be much more useful. They originated from Mesopotamia, which is in between the Tigris and Euphrates rivers. The Babylonian culture has dated back past 2000 b.c.
