# Adding 3-Digit Numbers Without Regrouping

We’ll learn to add 3-digit numbers with out grouping.

We all know methods to add 3-digit numbers with out including them. Let’s bear in mind by fixing some examples.

H T HE

5 7 2 → ﻿5 hundred + 7 ten + 2 one

+ 4 2 44 a whole bunch + 2 tens + 4 ones

9 9 6 9 hundred + 9 ten + 6 one

Solved Examples of Including 3-Digit Numbers With out Regrouping:

Including Two 3-Digit Numbers

1. The shopkeeper has 153 packs of chocolate chip cookies and 124 butter cookies. What number of cookies are there in whole?

 Resolution: We’ll do a set to search out out the entire variety of cookies. Stage 1: Add these first. 3 + 4 = 7 Step 2: Then add them. 5 + 2 = 7 Stage 3: Then add a whole bunch. 1 + 1 = 2 Thus, there are 277 cookies within the store.

Resolution:

 Stage 1: Prepare the numbers vertically. Step 2: Add these first. 1 + 5 = 6 Stage 3: Now, they add. 4 + 2 = 6 Lastly, add a whole bunch. 6 + 3 = 9 So 641 + 325 = 966

Including Three 3-Digit Numbers With out Regrouping:

In the identical means that we add two 3-digit numbers, we’ll add three 3-digit numbers.

For instance:

 1. Add 542, 234 and 103. Resolution: Stage 1: Prepare the numbers vertically. Step 2: Add these first. 2 + 4 + 3 = 9 Stage 3: Now, they add. 4 + 3 + 0 = 7 Step 4: Lastly, add a whole bunch. 5 + 2 + 1 = 8 So 542 + 234 + 103 = 879
