+60 | +2 | |||
| 26 | 86 | ? |
When adding numbers, it can be helpful to decompose the second number using the place value method and then use the arrow method to grow the first number by each place value
For example, if we have 225 + 653
- Decompose 653 into 6 hundreds, 5 tens, and 3 ones
- Grow 225 by +600 (=825)
- Grow 825 by +50 (=875)
- Grow 875 by +3 (=878)
