Calculators may be used on the ACT test. However, many problems do not require the use of a calculator to solve the problems. It may be best to work the problems and then check your answers with the calculator. This way a single button on the calculator does not give you a wrong answer. Moreover, always check to make sure your answer is logical.

The ACT math test also covers the basic geometric information including: circles, triangles, angles and parallel lines. In many cases, you may be asked to solve for (x) or determine the value of data.
