This simple worksheet is about inverses or opposites.

Example:

An inverse operation takes you back to your original number.

So, subtraction is the inverse of addition and vice versa.

     29 + 17 = 46.
     46 - 17 = 29.

and division is the inverse of multiplication.

     13 × 4 = 52.
     52 ÷ 4 = 13.
