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.

- FPGAhacker 5y agoSo you could multiply or divide two four digit numbers by visualizing them? To me that is pretty incredible!
- josephcsible 5y agoHow 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.
- aappleby 5y agoYeah 4x4 would be a bit much, 3x3 is doable, 3x2 is easy.
