Subtracting Hexidecimal

Subtracting Hexidecimal

Hello everyone,

I hope I am in the right forum.

Could someone please give me the rules for subtracting hexidecimals?

Thank you.

RE: Subtracting Hexidecimal

They're the same as for subtracting numbers in any other base.


If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.

RE: Subtracting Hexidecimal

Thank you for the reply. Now I realize I maybe having a little trouble with hex. Do you know of a website that I could go to to strengthen my knowledge in hex.

Thank you

RE: Subtracting Hexidecimal

As Salem says arithmetic in hexadecimal is the same as in decimal.
Decimal is base 10, there are  10 symbols 0,1,2,3,4,5,6,7,8,9.
10 in decimal is 1 ten and 0 units, 11 is 1 ten and 1 unit etc...
Hexadecimal is exactly the same except its base is 16, there are 16 symbols 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F (A-F representing the numbers 10 – 15)
10 in hex is 1 sixteen and 0 units, B in hex is 0 sixteen and 11 units, 2E in hex is 2 sixteen and 14 units.

Thank you OlafBogus,

Now I clearly understand how hex works.
