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)
