# Two Digit Addition Without Regrouping

In this section we will discuss two digit addition without regrouping. Up till now you have learnt single digit addition. Here first you will learn adding one digit number to a two digit number without carrying.
In two digit number, one number is in ones place and other number is in tens place.
1) At the top write T for tens and O for ones .
2) Write the number below it according to their places.
3) Put the plus sign (+ ).
4) Draw a line below the numbers.
5) First add the ones digit and then the tens digit.

Example 1: Add 34 + 5
Here 34 is a two digit number so write the numbers 3 and 4 according to their place values. So 3 is below tens (T) place and 4 is below ones place (O).
The second number is 5, which is one digit number so put it below 4.
 T O 3 4 + 5 ______ 3 9

Example 2: Add 53 + 4
Here 53 is a two digit number so write the numbers 5 and 3 according to their place values. So 5 is below tens (T) place and 3 is below ones place (O).
The second number is 4, which is one digit number so put it below 3.
 T O 5 3 + 4 ______ 5 7

Two digit addition by two digit
Example 1: Add 45 + 32
Here 45 is a two digit number so write the numbers 4 and 5 according to their place values. So 4 is below tens (T) place and 5 is below ones place (O).
The second number is 32 which is also a two digit number so write 3 below 4 and 2 below 5.
 T O    4    5 + 3    2   ______    7    7

Example 2 : Add 50 + 36
 T O    5    0 + 3    6   ______    8    6

For practice you can download the following and send me the feedback

 T O    8    4 + 1    4   ______ T O    3    8 + 2    1   ______ T O    2    4 + 5    4   ______ T O    6    1 + 3    8   ______ T O    7    1 + 2    6   ______ T O    1    7 + 2    2   ______ T O    8    4 + 1    3   ______ T O    3    8 + 4    1   ______ T O    1    5 + 4    3   ______ T O    5    2 + 3    3   ______
