One way to think about subtraction is that it’s “finding a missing part of a number,” where the “number” is the minuend aka, the sum, and the “missing part” is the “unknown addend.” Subtraction is just finding one of the numbers that make up another number, the minuend aka, the sum.

How do you use subtraction to find a missing addend in an addition problem?

If one addend and the sum are given, take the addend and subtract it from the sum. This will give you the missing addend. Don’t forget to always check your work by adding together the two addends to make sure they equal the sum.

Missing addends are exactly as the name implies, meaning addends that are missing from the mathematical equation. A statement like 4 + _ = 8 contains one known addend, one unknown or missing addend and the sum.
