_ + _ = Addition

Addition (symbol "+") is the mathematical operation of combining collections of objects together into a larger collection.

For example:

3 added to 2 (said "3 plus 2") can be calculated by adding 3 to 2: 

                  3 + 2 = 5.

As you can see in the picture, there are three apples and two other apples; which means that in sum we have five apples.
therefore,  3 + 2 = 5.
