-<u> 5.123</u> (borrow from 1 to make it 0 and make the 0 to the right of it a 10)
(now borrow from the 10 to make it 9 and make the other zero a 10)
7.100
-<u> 5.123</u> (now borrow from 7 to make it 6 and make the 0 to the right of it a 10)
7 (now borrow from the 10 to make it 9 and subtract the 2)
7.100
-<u> 5.123</u> (now subtract 1 from 10 and then subtract 5 from 6)
