For a while I’ve been meaning to memorize all the two digit squares but of course I then fail to practice them, so I’m not very far along. But that would help you with this too, not to mention you can start doing some square roots too.
For quick and dirty I’d probably just go with 37*38 = 40*40 -> 16% which is kinda close to 14% eh?
