How a problem works

Problems are read, not raced: there is no timer and no lives to lose. A first wrong answer gets a tip that uses that problem’s own numbers. A second shows the problem worked out step by step. Every wrong answer we plan for is tied to a named mistake, so the grown-ups’ dashboard can show where to help and why.
