Addition

Addition

Addition, represented by the plus sign (+), is a basic operation that combines together two individual values to give a total.

For example, 3 apples + 4 apples gives us a total of 7 apples. In number bonds (as shown below), 3 and 4 are the parts and 7 is the whole. In formal mathematics, 3 and 4 are known as the addends while 7 is referred to as the sum.
