When subtracting numbers, it can be helpful to decompose the second number using the place value method and then use the arrow method to decrease the first number by each place value
For example, if we have 875 - 239
- Decompose 239 into 2 hundreds, 3 tens, and 9 ones
- Decrease 875 by -200 (=675)
- Decrease 675 by -30 (=645)
- Decrease 645 by -9 (=636)
