Order of Operation Challenge

Order of Operation Challenge is a drill in one rule: the order in which the parts of an expression are worked out. Each question shows an expression and four possible answers, and only one of them comes from doing the steps in the right sequence.

That sequence is the one taught as BODMAS or PEMDAS, and the game spells it out. Brackets come first. Powers and square roots follow. Multiplication and division are next, taken from left to right, and addition and subtraction are last, again from left to right.

There are four modes, Easy, Normal, Hard and Pro, and the harder ones award more XP. Solving 15 questions moves you up a level. Each question has to be answered before its timer runs out, and the answer is picked with a mouse or touchpad.

Pick a mode: Easy, Normal, Hard or Pro. Read the expression, then solve it by working brackets first, powers and square roots second, multiplication and division third, and addition and subtraction last. Use a mouse or touchpad to choose the correct answer from the four options before the timer runs out. Solve 15 questions to move up a level.

Multiplication and division share a rank, as do addition and subtraction, so within each pair work strictly from left to right rather than doing one operation before the other. Clear the brackets before anything else, even when the sum outside them looks simpler. Harder modes pay more XP, so step up once Easy feels routine.

A multiple-choice maths drill on BODMAS and PEMDAS, played in a landscape frame. There are four modes, timed questions, 15 questions per level and XP that rises with the mode. Answers are chosen with a mouse or touchpad.

Traffic Control Math also gives you timed arithmetic answers to pick, with each right one turning a traffic light green. Math is easy! pairs expressions with their values, including roots and logarithms.
