Fun challenge!  I did this using basic Alteryx tools as well as tried using the Python tool for a "one tool solution".  My first attempt at creating a Python solution was very slow, so I took a second stab at it and it ran much faster.

My solution is a bit more messy, meaning that if we had a million columns to do calculations it would take a million times to apply the multi-formula tool. Not very practical. But it was what stroke first as a possible solution.

 

However, I post this solution because upon testing the calculated and the expected results I noticed an error of the magnitude of -13 which is probably to the machine error in the division in the multi-formula calculations.

 

I just noticed that before the test in the actual solutions the numbers are transformed to integers. Would this be considered a good practice? (Probably not if data involve big numbers)

Challenge done and attached. Reconciliation was hard as there is some inconsistency i the answer headers.
