key right there is you said "memorize." that's what is wrong, right there.
when faced with non-standard notation we should be able to just figure it out.
And there's always the option to take 3 halfway broken ones, and make 2 working ones out of those.
That's some fuzzy math.
Any program which runs right is obsolete.
