comment removing the remainder of a fraction
I want to define floor from first principles if possible. So knowing what x and y are, using basic arithmetic determine what the remainder is.

comment removing the remainder of a fraction
x and y are both integers. The output of f(x,y) is also an integer. Yes I need something like a floor function but I want it from first principles if possible

comment f(n) for rows with $2^x$ bits on
Thanks for the answer, i'm struggling to understand it though. Would you mind explaining the expansion a little, im not sure what you are iterating on n or x?

comment How to define this pattern as $f(n)$
Thanks for your help, I wanted to try steer clear of using a matrix though, the table was just to illustrate the problem.

comment How to define this pattern as $f(n)$
Fantastic! I love the simplicity of it. I tested it out by plugging in some values and it seems to do the trick. Thank you!

The summation goes from m=1 -> $2^n$ so if n = 3, then we will go from 1 -> 8

comment How to define this pattern as $f(n)$
I am trying to get m to correspond to the row, so if m=3 then we would be working on the third row and thus have 1xg(1)x1 = g(1) not sure if that makes sense...

I'm summing up to $2^n$ as this is the number of rows.

comment General solution for x of C = 100/(1+aX) + 100/(1+bX) … + 100/(1+zX)
I have tried finding some LCD and then tried to get X by itself but no luck, I have been trying to solve it with just the first 2 fractions by cross multiplying but cant even solve this lol

comment Change domain on series - Counting aplitudes
Thanks for this, I ended up creating my own version of this Kronecker delta function :) (((x-y)/(y-x))+1)/2 This gives me 1 when x=y and 0 for anything else
