You notice that this is an addition of two like terms (2=2).

The plus sign signifies that the terms 2 and 2 are combined together to yield 4.

The result (4) of addition of these terms, is expressed with an equal sign such that:

`2 + 2 = 4`

If you need to verbalize `2 + 2 = 4`  you need to say " two plus two yields four).

Hence, adding two positive like terms yields the double of the term such that: `2 + 2 = 2*2 = 4` .
