Mathematics has been used since ancient times, first developing with counting. It is useful in many areas of modern life like business, cooking, and art. Mathematics is the science of shape, quantity, and arrangement, and was used by ancient Egyptians to build the pyramids using geometry and algebra. Percentages can be understood using currency denominations, and fractions can be seen by dividing fruits and vegetables. Geometry, arithmetic, and calculus are applied in fields like construction, markets, engineering, and physics. Mathematics underlies structures and is important for careers requiring university degrees.
