Tap operation chips to collapse an expression with negatives, exponents and nested parentheses in any order you like — a wrong order leaves a visibly wrong value, and LOCK IN checks the final number.
Every operation sitting between two numbers is a tappable chip, so you choose which sub-expression collapses next; collapse in the right order and the value is correct, collapse out of order and the wrong number appears with a diagnosis of the exact step that broke the rule. Target mode makes you pick a non-standard order to hit a given value (your order becomes the parentheses), and Twin mode sets −3² beside (−3)² so the sign difference is seen, not told. It drills 7.NS.3 and 7.EE.3 and targets the −a² versus (−a)² and left-to-right subtraction misconceptions. Best for Grades 7–8.
A free, no-signup, no-ads math game for Grades 7–8 — practising order-of-operations, negative-numbers, exponents, parentheses. Play in your browser on the KidsDoMath games hub or explore more Arithmetic games.
