About Mixed Addition and Subtraction

What this skill is

Evaluating mixed addition and subtraction reinforces that addition and subtraction share equal precedence and must be executed in left-to-right order as they appear.

When children learn it

Taught in 3rd and 4th grade as preparation for formal multi-operation order of operations rules (CCSS 3.OA.D.8).

Teaching Tips

  • Explain that addition and subtraction are equal twin partners: when they appear together with no parentheses, always read them left-to-right like a book. Solve the first two numbers, rewrite the new total, and then finish the problem.

Common Mistakes

  • Always doing addition before subtraction regardless of written position (e.g., solving 10 - 4 + 2 as 10 - 6 = 4 instead of 6 + 2 = 8).
  • Skipping around in the equation rather than following strict left-to-right reading order.
  • Calculation slips when expressions have four or more terms.
