Subtraction in Hexadecimal
There are many ways to do hexadecimal subtraction. Here is one of them.
The problem here is E is bigger than B so borrowing is required to perform the subtraction. Starting in the right hand column borrow a 1 from the next column. 4-1 =3
Use that borrowed “sixteen” as an E and its hex complements
10Hex E = 2
Just recited the alphabet starting at E ie “count” past E, F, G. Smile.
G is really 10 in hexadecimal.
The E that was borrowed is subtracted leaving only the 2
Addition is now used to generate the right hand digit of the answer.
Borrow 1 from the D.
Substitute a C and 4 for the 10Hex
Simple addition completes the next column.
The left hand column is completed without any borrowing.
Have fun and let me know how easy this is to read.
