How Does Addition and Subtraction Relate to Counting Addition and subtraction are the two most basic operations in counting. In simple terms, it is just like moving forward and backward. The addition means going forward for such as 6 + 1, or 4 + 3 and subtraction means going backward such as 5 - 2 or 9 - 7. Let’s learn these two operations separately. Addition is the operation in which we count two different set and then add them together, or we simply add numbers together. In addition, the answer is always bigger than all the numbers combined in the process, i.e. 4 + 3 = 7. We can see that 7 is greater than 4 and 3. In normal subtraction, we remove a smaller number from the bigger number and then count what is left. For example, when we see the equation 5 – 2, it means 2 will be removed from the number 5. When 5 is removed from 2, the answer is 3. As mentioned earlier, subtraction means counting backwards, which is, in this case, means moving two spaces back from 5. i.e., 5, 4, 3, 2, 1. When we jump two spaces back, we get 3. These are two most interchangeable mathematical operations there are. You will get a great deal of use out of these worksheets.
