A crucial math operation!
Adding 3-digit numbers with regrouping can seem challenging at first, but with some practice, you'll become a pro in no time!
Here are some examples and tips to help you master this skill:
Example 1:
456 + 278 = ?
Step 1: Add the hundreds place: 400 + 200 = 600
Step 2: Add the tens place: 50 + 70 = 120
Step 3: Add the ones place: 6 + 8 = 14
Regrouping: Carry the 1 from the ones place to the tens place: 120 + 1 = 121
Answer: 734
Example 2:
342 + 195 = ?
Step 1: Add the hundreds place: 300 + 100 = 400
Step 2: Add the tens place: 40 + 90 = 130
Step 3: Add the ones place: 2 + 5 = 7
Regrouping: None needed in this example
Answer: 537
Tips:
1. Break down the numbers: Split each number into hundreds, tens, and ones places.
2. Add each place value separately: Start with the hundreds place, then move to the tens place, and finally, the ones place.
3. Regroup when necessary: If the ones place has a value greater than 9, carry the extra 1 to the tens place.
4. Check your work: Verify your answer by calculating the sum in a different way.
Practice, Practice, Practice!
Try these practice problems:
* 475 + 216 = ?
* 936 + 432 = ?
* 189 + 275 = ?
Remember to follow the steps and regroup when necessary. The more you practice, the more confident you'll become in adding 3-digit numbers with regrouping!
