Multiplying with Regrouping
Grade 4 · Math · Multi-Digit Multiplication · Hawaii, USA
Lesson Summary
When a product in one column is 10 or more, you need to regroup. This means carrying a digit to the next column.
Explanation
Regrouping happens when the product of two digits is 10 or more. For example, in 68 × 4, start with 8 × 4 = 32. Write the 2 in the ones place and carry the 3 to the tens column. Then multiply 6 × 4 = 24, and add the 3 you carried to get 27. The final answer is 272. Always start multiplying from the ones place and work to the left. Regrouping is just another word for carrying.
