Proper deep dives — not quick tips. Each one walks you through a whole topic chapter by chapter, shows you why the maths works, teaches the fast mental tricks, and lets you try each idea straight away.
Every "Try it" you solve is worth XP. Finishing a whole masterclass earns a bonus and a trophy.
Pick a topic. You get the points worth remembering, then a ten-question review quiz drawn from that topic only. Good before a test, or straight after finishing a masterclass.
Short shortcuts, not long lessons. Open one, read the rule, try it once, and it is yours. These are the moves that make you look fast.
