An unknown addend is a number that is missing from an addition equation, making it necessary to find that value to complete the equation. For example, in the equation (5 + x = 12), (x) is the unknown addend. Solving for (x) reveals that it is 7, as (5 + 7 = 12). Identifying unknown addends is a common task in basic arithmetic and algebra.
