When adding two numbers, if the ones digits add up to 10 or more, we write the ones digit and carry the tens digit over to the tens column.
Quick revision
Remember these!
- Regrouping used when ones digits sum to 10+.
- We write ones digit, carry tens digit over.
- Example: 27+15, 7+5=12, write 2, carry 1.
- Then 2+1+1=4, giving 42.
- We start from the ones column.
- This helps add larger numbers accurately.
- Regrouping is also called 'carrying'.
- Practice builds confidence with bigger numbers.
