What I usually do is I take the numbers and flip it so now it's 538-247 which equals 291 but since I had to flip it I put a - sign in front of my answer
so 247-538 is -291
so 247-538 is -291
538
-247
-------
291
8-7 = 1
You can't do 3-4 so you borrow 10 numbers from 5 and get 13-4=9.
4 - 2 = 2
-247
