Why do pilots need maths?

It depends on what kind of airplane pilot we are talking about - most general aviation pilots use simple math to calculate weight and balance (multiplication and division), time and distance calculations, time zones (addition and subtraction) etc.

To be a professional airline pilot, most pilots are required to learn lower division calculus but will probably never use that information in the air, particularly with all the new computer technology.
