Add 75 + 8

Answer:

How many columns will I need?

Log(What ever number that you are trying to scale) / Log(radix)

Log of 75 /Log of 16(radix) = 1.55

Always round up if there is a remainder.

We will need 2 columns!

EACH col represents ? bits

? bits + ? bits

COLUMNS    16-1

BIT VALUE   5  B

BIT VALUE   0  8
