I've been working through some #soroban exercises try to actually become reasonably proficient in its use. Interestingly enough, I'm doing much better with multiplicaiton/divison than I am with the addition/subtraction questions, but that's because the latter involve summing a column of values rather than just multiplying two numbers. There are more places to screw up.

Still, these questions seem designed to deliberately screw me up with things like multiple carries, changing the value on a rod just to immediately revert that change, etc.

Still, it's probably that way for a reason.
