Mathematics is applied directly and indirectly in many aspects of daily life. [Geometry is used in nature like honeycomb cells and in car design with circles, rectangles, and quarter spheres.] [Medicine uses protein modeling and geometry.] [Engineering applies math to determine materials and solar energy.] [Forensics uses calculus to clarify blurred images.] [Trigonometry helps find heights of objects.] [Number theory creates codes and helps with bulk purchasing costs.] [Calculus studies change and is used in acceleration, satellite movement, and more.] Mathematics plays a key role in many fields.
