Subtraction can be thought of as removing one quantity from another. To subtract 7 – 3, place 7 cubes and then remove 3 of them. There are 3 cubes remaining, so 7 – 3 = 4. Subtraction can also be thought of as finding the missing addend in a sum. So 7 – 3 is like asking 3 + ? = 7. The missing addend is 4 because 4 must be added to 3 to make 7.
