# Adding 2-digit numbers without regrouping 1

• What does it mean by "regrouping" and "without regrouping"?
• Regrouping means to make ones into tens to make addition easier. For example, add 36
_________________________________________________________________ +27
In order to do this, you will have to start adding on the right side. If you add 6 and 7, you will get 13. But, you can't put 13 down below the 7. So, you will have to put a 3 below the 7, and "carry" the 1 to the right side. When you add the right side, you will do 3+2+1. This is regrouping. When you do addition without using this method of "carrying the number", it is "without regrouping".
• can someone tell me when we will use this in real life?
