| − | For simple addition, it is easy to add by counting steps. If we consider 6 + 4, then we can start at 6, then add 1 four times - 7, 8, 9, 10. Thus, 6 + 4 is 10. | + | For simple addition of [[whole number]]s, it is easy to add by counting steps. If we consider 6 + 4, then we can start at 6, then add 1 four times - 7, 8, 9, 10.
