# How to Add with and without Regrouping

In this post, we are going to learn how to do addition problems with and without regrouping.

### How to Add without Regrouping

• Place the addends one on top of the other so that the place values fall in the same columns.
• Add each column together separately, starting with the 1s place.
• The sums go below each column, underneath the line.

Let’s take a look at an example adding 83 + 14.

We start by writing the number 83 and below it, the number 14, making sure to line up the 1s columns, or in other words, the 3 and 4.

We then add 3 + 4 = 7 and write it underneath the 1s place column. Then, we add 8 + 1 = 9 and we write it under the 10s place column. And we get the answer 97.

### How to Add with Regrouping

If we get a two digit number while adding the first column together, we add that number to the 10s place column.

Let’s check out an example adding 46 + 27.

First, we write the 46 underneath, making sure to line up the 1s place columns and lastly, we write down the 27.

We first need to add the 1s place numbers 6 + 7 = 13, we need to put the 3 underneath the 1s place column and add the 1 to the 10s place column.

1 + 4 + 2 = 7, we write the 7 underneath in the 10s place column. If you want to practice these kinds of problems, and more, go to Smartick and try it for free!
