Two plus two is four (or 4 in written form). Why? Well, by beginning at the origin which is 0, we can count up to 5.
0, 1, 2, 3, 4, 5
Two plus two is a representative expression of the value initially being at 2, and adding two more values to the 2 that we already have. Since we are adding two to the quantity we already have, we can see that the answer is four (4) because we can simply count up two numbers from 2 to get what 2 + 2 equals. When counting up, we do not count the number that is already begun with because that would invalidate the equation. Since three (3) is after two (2), we can count starting at three. 3, 4! Those are the two values we get to when in the process of adding two. When we add one to two, we get three. When we add two to two, we get four. That is why 2 + 2 = 4.
