4 Digit Addition

4 digit addition involves adding numbers that have four digits. When adding 4 digit numbers, it is important to align the digits according to their place value - thousands, hundreds, tens, and ones.

Steps for 4 Digit Addition:

1. Align the numbers vertically according to their place value.
2. Start adding from the rightmost column (ones place) and move towards the left.
3. Add the digits in each column, carrying over to the next column if the sum is greater than 9.
4. Continue this process for each column until all columns have been added.

Example:

Let's add the following 4 digit numbers: 3,245 + 1,678.

Starting from the rightmost column (ones place):

5 + 8 = 13 (carry over 1, write 3)

4 + 7 + 1 (carried over) = 12 (carry over 1, write 2)

2 + 6 + 1 (carried over) = 9

3 + 1 = 4

So, the sum is 3,245 + 1,678 = 4,923.

Study Guide:

• Understand place value: Ones, tens, hundreds, thousands.
• Practice adding 4 digit numbers using the vertical alignment method.
• Learn to carry over when the sum of a column exceeds 9.
• Work on problems involving carrying over multiple times.
• Master the addition facts for single digit numbers.

With practice and understanding of place value and carrying over, you can become proficient in adding 4 digit numbers!
