Order of Operations

  • When evaluating a numerical expression, follow the standard order of operations: first evaluate powers, then multiply and divide from left to right, then add and subtract from left to right. BUT: parentheses and other grouping symbols (fraction bar, brackets, etc) always override the standard rules. Always work within grouping symbols first.

  • If the expression contains variables, substitute the values that are given for the variables and then use the rules for order of operations on the resulting numerical expression.
