Type any expression and see it solved one operation at a time with the reason for each step — no calculator tricks, no guessing. Then take the 5-question practice round with worked solutions. Everything is computed locally, never sent anywhere.
Why it matters: 2 + 3 × 4 is 14, not 20. If you multiply first, the answer is 14; left-to-right blindly gives the wrong answer — this is the single most common maths slip in school exams.
