Mechanical engineers require mathematics to perform engineering duties in planning and designing tools, engines, machines, and other mechanically functioning equipment; they oversee installation, operation, maintenance, and repair of such equipment as centralised heat, gas, water, and steam systems. Mechanical engineers use math for many different reasons like using physics formulas to determine things like energy and force, using algebra to design suspension systems or developing algorithms for computer software. The field requires proficiency in algebra, geometry, calculus, statistics and differential equations.
