Hex Addition and Subtraction

Hex Addition

e.g we have a hex number 23D9 and we want to add it to 94BE.

  23D9

+94BE

  B897

because as above 9+E(14)=23

23-16=7 WITH CARRY

Now in next step , 1+D(13) + B(11)=25-16=9 WITH CARRY....

Next step, 3+4+1=8

Since there is no carry this time 9+2=11(B).

HEX Subtraction

Say we want to subtract 59F and 2B8

59F

2B8

2EF

because as above F(15)-8=7

9+16=25, Now 25 will be subtracted from B(14)=25-11=14(E) with borrow from 5

4-2=2.
