Here we will learn adding 2digit numbers without regrouping and start working with easy numbers to get acquainted with the addition of two numbers.
We are going to start working with the basic addition of twodigits with everything arranged because this is what we will always do with bigger numbers in future.
How to add two twodigit numbers without carrying?
Let’s follow the steps and start learning adding 2digit numbers without regrouping with the help of an example.
1. 26 + 41
(i) 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 first the ones' place digits. (6 + 1 = 7).
(iii) Then add the tens' place digits. (2 + 4 = 6).
(iv) The answer of 26 + 41 = 67.
Method II: 26 + 41
26 = 2 tens + 6 unit → addendSo, adding 26 + 41 = 67.
Follow the steps of another example of adding 2digit numbers.

(ii) Add first the ones' place digits. (3 + 2 = 5).
(iii) Then add the tens' place digits. (5 + 3 = 8).
(iv) The answer of 53 + 32 = 85.
