Regrouping in addition is the process of combining two or more numbers by adding their digits and then simplifying them to get the final answer. Here are a few examples:
Adding Two Numbers
1. 45 + 27 = ?
Regrouping step:
* Add the two numbers: 4 + 2 = 6
* Add the remaining digits: 5 + 7 = 12
* Combine the two results: 6 + 12 = 18
Answer: 45 + 27 = 72
Adding Three Numbers
1. 34 + 27 + 16 = ?
Regrouping step:
* Add the first two numbers: 3 + 2 + 7 = 12
* Add the remaining digits: 4 + 6 + 16 = 26
* Combine the two results: 12 + 26 = 38
Answer: 34 + 27 + 16 = 77
