Final answer:
The Babylonians made important contributions to geometry, algebra, and trigonometry.
Step-by-step explanation:
The Babylonians made important contributions to geometry, algebra, and trigonometry. In geometry, they introduced the concept of measuring angles using a 360-degree system. They also developed a complex system of arithmetic that formed the basis of mathematics in the ancient Mediterranean world. In algebra, they created the concept of Arabic numerals, which are still used today. Lastly, in trigonometry, they had knowledge of the relationship between the sides and hypotenuse of a right triangle and could solve quadratic equations.
