Mixed operations are math problems that use both addition and subtraction in the same set of exercises. These problems help you practice when to add and when to subtract.
Mixed operations problems may include both addition and subtraction, but the answers will stay within 20.
Addition problems use the plus sign (+) to show putting numbers together. Subtraction problems use the minus sign (-) to show taking numbers away.
Always look carefully at the operation signs to decide whether to add or subtract.
To solve mixed operations, work from left to right unless parentheses are used. Solve one step at a time.
Do not skip steps. Solve in order from left to right to get the correct answer.
