Master Three-Digit Addition Easily: Step by step guide for addition

Adding numbers is an important math skill that helps us in everyday life. In this guide, we will learn how to add three-digit numbers in a simple and fun way.

What Are Three-Digit Numbers?

A three-digit number has three parts:

• Hundreds place (the first number on the left)
• Tens place (the middle number)
• Ones place (the last number on the right)

For example, in 452:

• 4 is in the hundreds place (it means 400)
• 5 is in the tens place (it means 50)
• 2 is in the ones place (it means 2)

Steps to Add Three-Digit Numbers

Step 1: Write the Numbers in Columns

Align the numbers properly by place value:

   267

 + 438

Step 2: Add the Ones Place

• Add 7 + 8 = 15
• Write 5 and carry over 1 to the tens place.

Step 3: Add the Tens Place

• Add 6 + 3 = 9, then add the carried-over 1 → 9 + 1 = 10
• Write 0 and carry over 1 to the hundreds place.

Step 4: Add the Hundreds Place

• Add 2 + 4 = 6, then add the carried-over 1 → 6 + 1 = 7
• Write 7.

Now, we get:

   705

So, 267 + 438 = 705

Tips to Make Addition Easy

• Line up numbers correctly (ones under ones, tens under tens, etc.)
• Start from the right (begin with the ones place)
• Carry over when needed (if the sum is 10 or more, move the extra digit up)
• Double-check your work (re-add the numbers to be sure)

Where Do We Use Three-Digit Addition?

We use addition in many real-life situations, such as:

• Shopping: Adding up prices of different items
• Trips: Calculating the total distance traveled
• Saving Money: Adding up your savings from different months
