How to Add Four 4-Digit Numbers Using Column Addition
FAQs on Class 4 Maths: Add Four 4-Digit Numbers in Columns
1. How to add 4-digit numbers in columns?
To add four 4-digit numbers in columns, you must align them vertically and add each column from right to left. This method, known as column addition, ensures that you are adding the correct place values together.
Here are the steps:
- Align the Numbers: Write all four numbers one below the other, making sure the ones, tens, hundreds, and thousands digits are in straight columns.
- Add the Ones: Start by adding the digits in the rightmost column (the ones place).
- Carry Over: If the sum of a column is 10 or more, write the last digit of the sum below the line and carry the other digit(s) to the top of the next column on the left.
- Repeat for All Columns: Continue adding each column from right to left (tens, hundreds, thousands), remembering to include any numbers you carried over.
2. What is column addition with carrying?
Column addition with carrying, also known as regrouping, is a technique used when the sum of the digits in any column is 10 or greater. Instead of writing a two-digit number under a single column, you carry the 'tens' part of the sum over to the next column to the left.
For example, if the sum in the ones column is 25, you would:
- Write the 5 below the ones column.
- Carry the 2 over to the top of the tens column to be included in its sum.
This process is essential for correctly solving addition of large numbers.
3. How do you add four large numbers together?
Adding four large numbers, such as four 4-digit numbers, follows the exact same principle as adding two numbers using the column addition method. The key is to be systematic and careful with your calculations, especially when dealing with more numbers in each column.
Simply stack all four numbers vertically, ensuring the place values align. Then, add each column one by one, starting from the ones place and moving left, making sure to handle any carrying at each step.

8. Why is it important to align numbers correctly in column addition?
Aligning numbers correctly is the most critical first step in column addition because it ensures you are adding the correct place values together. Misalignment, such as adding a 'tens' digit to the 'ones' column, is a very common mistake that leads to incorrect answers.
Proper alignment means:
- Ones are added with ones.
- Tens are added with tens.
- Hundreds are added with hundreds, and so on.

- Read Carefully: Read the entire word problem to understand the scenario.
- Identify the Numbers: Find all the 4-digit numbers that need to be added together.
- Set Up the Sum: Write these numbers down in a vertical column, ensuring correct alignment.
- Solve: Perform the column addition, paying close attention to carrying, to find the final sum.
10. How does this worksheet help with concept retention?
This worksheet reinforces concept retention by providing a mix of activities that target different aspects of learning 4-digit addition. Instead of just one type of problem, it includes varied exercises to keep students engaged.
Features that aid retention include:
- Direct Practice: Standard column sums build muscle memory.
