I ran the instance yesterday for the first time and found the fight to be quite fun. Nothing was explained but it was pretty straightforward to me on how the math worked. Math tends to be not liked very much (including by me) so it's not surprising and understandable to see people having issues with it though.

I didn't know dyscalculia was even a thing until I saw this topic. Thank you for teaching me something new.

I say use whatever tool you need in order to do the mechanic successfully.
