1. What did the Babylonians, Egyptians, Greeks, Romans, Islamic, and Chinese contribute to mathematics?

Babylonian: The base 60 system that is still used today in the division of hours into minutes and seconds. They left clay tables that contained tables of multiplication, division, squares cubes, and square roots, and the measurement of area and length. All of these allowed the solution of linear and quadratic equation to be determined. They knew the Pythagoras Theory before invented and made predictions of when an astronomical event will occur.
Egyptians: 1- Used math to solve practical problems (measuring time, the annual Nile flooding, calculating area of land, bookkeeping, accounting, calculating taxes). 2- Introduced Approximation by giving the approximate area of a circle. 3- Introduced the base 10 counting system they used for measuring time, flood, areas and records.
Greeks: used math for music, made Pythagorean theorem, Euclidean algorithm, latitude and longitude, buoyance, pi, exponents, odometer.
• Pythagoras (theorem, discovered the square root of two p/q) and Thales (stated that since ABC are points in a circle, AC must be the diameter and the angle computer design.
The American Census couldn’t keep up with population growth that was done in paper.
1890 Census Count- Herman Hollerith- created an option of counting populations instead of human counting (with punch cards).
Computing machines- railroads (first failed, then won)
1924- Watson rename the IBM.
