Hex Subtraction

Subtracting Hex Numbers

  • If the second digit is greater than the first, borrow 16 from preceding digit.
Subtract 59F – 2B8.
F9F(8 from 15 = 7)
-2B8(11 from 25 (9+16) = 14(E))
(2 from 4 (5-1) = 2)
=2E7

Subtract F88 – 9B8.
F88(8 from 8 = 0)
-9B8(11 from 24 (8+16) = 13(D))
(9 from 14 (15-1) = 5)
=5D0
