Fractions

Sometimes a mathematical equation requires more than one operation. It may be necessary to add, subtract, multiply and divide several numbers to answer one question. The Order of Operations is a set of rules that determine the order in which different operations are performed. Apply the rules outlined below.

Rules of Arithmetic Operations

Rule 1

If the operations are only addition and subtraction (+, –), do them from left to right.

Example:

Subtract . Then add .

Rule 2

If the operations are only multiplication and division (x, ÷), do them from left to right.

Example:

Multiply . Then divide the answer by .

Rule 3

If there is a mixture of addition, subtraction, multiplication and division (+, –, x, ÷), do the multiplication and division before the addition and subtraction.

Example:

Divide . Then subtract the answer from .

Rule 4

If there are brackets, do the operations inside brackets first.

Example:

First, add all the fractions inside the brackets. Then multiply the answer by . Finally, subtract from that answer.
