# Addition of 3-Digit Numbers with out Regrouping

We’ll be taught Addition of 3-Digit Numbers with out Regrouping.

We all know find out how to do addition of 3-digit numbers with out regrouping. Allow us to recollect it fixing some examples.

Add 572 and 424.

H     T     O

5     7     2    → ﻿5 a whole bunch + 7 tens + 2 ones﻿

+   4     2     4    → 4 a whole bunch + 2 tens + 4 ones

9     9     6     9 a whole bunch + 9 tens + 6 ones

Solved Examples on Addition of 3-Digit Numbers with out Regrouping:

Addition of Two 3-Digit Numbers

1. The shopkeeper has 153 packets of chocolate cookies and 124 butter cookies. What number of cookies are there in all?

 Resolution: To seek out out the entire variety of cookies, we are going to carry out addition. Step 1: First add those.              3 + 4 = 7 Step 2: Subsequent add the tens.             5 + 2 = 7 Step 3: Then, add the a whole bunch.             1 + 1 = 2 Thus, there are 277 cookies within the store.

2. Add 641 and 325.

Resolution:

 Step 1: Prepare the numbers vertically. Step 2: First add those.            1 + 5 = 6 Step 3: Now, add the tens.             4 + 2 = 6        Lastly, add the a whole bunch.             6 + 3 = 9 Thus, 641 + 325 = 966

Addition of Three 3-Digit Numbers With out Regrouping:

We’ll add three 3-digit numbers in the identical approach as we add two 3-digit numbers.

For examples:

 1. Add 542, 234 and 103. Resolution: Step 1: Prepare the numbers vertically. Step 2: First add those. 2 + 4 + 3 = 9  Step 3: Now, add the tens. 4 + 3 + 0 = 7 Step 4: Lastly, add the a whole bunch. 5 + 2 + 1 = 8 Thus, 542 + 234 + 103 = 879
