How do you add two digit numbers with regrouping?

(i) First arrange the numbers vertically so that the tens’ place digits and ones’ place digits are lined up which means in simple one number should be written above the other number. Draw a line under the bottom number. (ii) Add the ones place digits. Add (5 + 7 = 12).

How do you do 2 digit numbers without regrouping?

Add 2-Digit Numbers Without Regrouping

1. Place one number above the other number so that the tens’ place digits and ones’ place digits are lined up. Draw a line under the bottom number.
2. Add the two ones’ place digits. (2 + 3 = 5).
3. Add the numbers in the tens’ place column (4 + 5 = 9) and place the answer below the line and to the left of the ones’ place sum.
