The ancient Babylonians were skilled calculators, and their calculation programs were realized with the help of multiplication tables, reciprocal tables, square tables and cubic tables. The Babylonian method of writing numbers is more noteworthy.
The Babylonians introduced a numerical system (hexadecimal) based on 60, and the Greeks and Europeans also applied this system to mathematical calculation and astronomical calculation until16th century. Until now, hexadecimal is still used to record angles, time and so on.
Extended data:
Babylonians have rich knowledge of algebra, and many clay tablets contain problems of linear and quadratic equations. Their process of solving quadratic equations is consistent with today's collocation method and formula method. In addition, they also discussed some cubic equations and multivariate linear equations.
During BC 1900-BC 1600, a table of numbers (No.322, purington) was recorded, and it was found that there were two groups of numbers, namely, the hypotenuse length of a right triangle with an integer side length and the side length of a right angle, from which the side length of another right angle was deduced, that is, the indefinite equation X2+Y2=Z2 was obtained.
