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.
To find an unknown addend, you can use the equation format of addition. For example, if you have the equation (a + b = c) and need to find (b), rearrange the equation to isolate (b) by subtracting (a) from both sides: (b = c - a). This will give you the value of the unknown addend.
Sum
addend+addend=sum
correct.
Addend plus Addend equals Sum.
