This math video tutorial looks at order of operations as it is applied to problems containing mixed fractions. The order of operations specifies that if a problem contains some combination of calculations, the multiplication and division components must be completed before the addition and subtraction ones.

The instructor uses several problems to illustrate the steps required, including converting mixed fractions to improper ones; carrying out operations in the correct order; and reducing the resulting fraction to its simplest form.

The problems get more complicated as the video progresses.
