    Lightbulb Hexadecimal relationship to a changing input?

    Hello, I am trying to find the relationship of an input to output based on constant variable.


    Why/How does GH change based on constant IJ with 2H, 5H, 8G/8H respectively?


    Three examples shown below.
    1. Resultant: 1G 1H with variable 1I 1J when 2H=30
    2. Resultant: 4G 4H with variable 4I 4J when 5H=31
    3. Resultant: 8G 8H with variable 4I 4J when 8G=31 8H=31


    A B C D E F G H I J
    1 6 A D 0 7 D A C 9 C 2 A 5 C 1 7 A C B 1
    2 30 30 30 30 30 30 30 30
    3 0 0 0 0 0 0 0 0

    4 6 A D 0 7 D A C 9 C 2 A 7 4 9 F A C B 1
    5 30 30 30 30 30 30 30 31
    6 0 0 0 0 0 0 0 1


    7 6 A D 0 7 D A C 9 C 2 A 9 C D 2 A C B 1
    8 30 30 30 30 30 30 31 31
    9 0 0 0 0 0 0 1 1

    Hey badracer1.

    Hint - Can you come up with some equations for this?

    [Also note that you can use base 16 in your equations.]

    Hi Chiro, I would love to do that! I was wondering if there is a way to write an equation when all the variables and resultant is known?

    Re: Hexadecimal relationship to a changing input?

    If you have a value say ABCD_Hex then you can write out:

    Value = 16^3*A + 16^2+B + 16*C + D.

    From that you can set a function with the ABCD in hexadecimal.

    Using the above can you write some sort of equation or relation you'd like to solve?

    Chiro, Thanks for the reply! Um I think you mean: 9CD2 =(16^3*9) + (16^2+12) + (16*13) + 2?
