Written addition
Practise column addition with carrying across tens, hundreds, thousands, and ten-thousands.
How to solve this
- Write ones under ones, tens under tens, hundreds under hundreds; most wrong answers start with misaligned columns.
- Add from the ones place and carry when a column reaches 10 or more.
- Estimate first: 48,205 + 17,698 is about 66,000, so 65,903 is plausible.
Examples
3,482 + 5,769
9,251
48,205 + 17,698
65,903
12,340 + 8,760
21,100
