Question

What contribution did Al-Khwarizmi make to the world of mathematics?

A. He created the number system based on Chinese number system

B. He developed the formula and process used to make Persian rugs.

C. His work became the basis for algebra.

D. He determined the formula for finding the hypotenuse of a right triangle.

Answer 1

C, Not A or B. and definitely not the chinese number system.

Answer 2

Step-by-step explanation:

The answer is C.

He may have made a contribution to D. There are over 360 different proofs for the Pythagorean theorem but that would not be his major contribution.

B may also be true, but if it is, he is not noted for it.

A not the Chinese system.

His main contribution was in the solution of equations like

y = 2x^2 + 20x + 12 = 2(x^2 + 10x + 25) - 12 = 2(x + 5) - 62 (completing the square) which we teach in the lower grades now, but when you learn something about the number system used, you realize that any contribution is remarkable.
