Architects use math in several areas of design and construction, from planning the blueprints or initial sketch design to calculating potential structural problems that a site may encounter. Architects employ geometry, for example, when they use the Pythagorean theorem to calculate the size and shape of a structure.

Before becoming certified as an architect, a person takes several math classes to prepare, including algebra and calculus. These are studied as part of the degree program a person must complete before later participating in an internship and obtaining proper license and certification based on the area in which he plans to work.
