Adding double-digit numbers can be super easy when there’s no regrouping (carrying). In this post, we’ll learn how to solve these problems step-by-step, with simple examples you can try yourself!
What is Double-Digit Addition Without Regrouping?
When you add two-digit numbers and each place value (ones and tens) adds up to less than 10, you don’t need to regroup (or carry). This makes the addition quick and simple!
For example:
Here, when you add the ones and tens, each sum is less than 10. Let’s break it down!
Step-by-Step Guide
Let’s solve the problem 23 + 41 together!
- Add the Ones Place
Look at the numbers in the ones place: 3 and 1. - Add the Tens Place
Now, look at the tens place: 2 and 4. - Put It Together
The final answer is 64!
More Practice Examples
Here are a few more examples to try!
- 35 + 42
- Ones: 5 + 2 = 7
- Tens: 3 + 4 = 7
- Answer: 77
- 51 + 32
- Ones: 1 + 2 = 3
- Tens: 5 + 3 = 8
- Answer: 83
- 12 + 54
- Ones: 2 + 4 = 6
- Tens: 1 + 5 = 6
- Answer: 66
Why Is This Important?
Practicing double-digit addition without regrouping helps kids:
- Build confidence in math.
- Master the basics of addition.
- Prepare for more challenging problems with regrouping later on.
Tips for Practicing
- Write the numbers clearly and line up the ones and tens.
- Check your work by adding the numbers again.
- Use fun tools like number lines or counters to help visualize the sums.
Final Thoughts
Double-digit addition without regrouping is a great way to practice basic math skills. Once you get the hang of it, you’ll be ready to tackle regrouping in no time!
