## How to Solve Three Digit Addition Problems

Performing three-digit addition problems involves adding numbers from right to left (ones place to hundreds place) while carrying over when necessary. Here’s a step-by-step guide that teachers can share with their students to help them in solving three-digit addition problems:

**Step 1 – Write the Numbers**

Write the numbers you want to add, aligning them vertically by their place values (ones, tens, and hundreds). Make sure the digits in each place value column line up.

Example: Add 253 and 127.

**Step 2 – Add the Ones Place**

Start by adding the digits in the ones place (the far right column). Write the sum below the line, in the same column. If the sum is greater than 9, write down the last digit and carry over the remaining digit(s) to the next column (tens place).

**Step 3 – Add the Tens Place**

Add the digits in the tens place, along with any carry-over from the previous step. Write the sum below the line, in the same column. If the sum is greater than 9, write down the last digit and carry over the remaining digit(s) to the next column (hundreds place).

**Step 4 – Add the Hundreds Place**

Add the digits in the hundreds place, along with any carry-over from the previous step. Write the sum below the line, in the same column.

**Step 5 – Check Your Answer**

Look over your work to make sure you haven’t made any mistakes. Optionally, you can use a calculator or another method (like subtraction) to verify your answer.

In this example, the sum of 253 and 127 is 380.
