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
Rules of Arithmetic Operations
If the operations are only addition and subtraction (+,
), do them from left to right.
Subtract . Then add .
If the operations are only multiplication and division (x,
Ã·), do them from left to right.
Multiply . Then divide the answer by .
If there is a mixture of addition, subtraction, multiplication
and division (+, , x, Ã·), do the multiplication and
division before the addition and subtraction.
Divide . Then subtract the answer from .
If there are brackets, do the operations inside brackets
First, add all the fractions inside the brackets. Then
multiply the answer by . Finally, subtract from
