Surely it isn't that rare? I can track about 8 digits total while doing mental mul/div, and I don't think of that as anything special.

So you could multiply or divide two four digit numbers by visualizing them?
To me that is pretty incredible!

How do you figure? Just the two inputs would take up all 8 digits, but you need to keep track of a bunch of intermediate results too.

Yeah 4x4 would be a bit much, 3x3 is doable, 3x2 is easy.

I’m probably just an idiot, but I am absolutely terrible and anything that requires me to retain information in my head for a calculation.
