Order of Operation Challenge
Expressions that are only hard if you do them in the wrong order.
Follow the order of operations to solve each expression. Use BODMAS / PEMDAS rules. Solve brackets (parentheses) first, then powers and square roots. Next, solve multiplication and division from left to right. Finally, solve addition and subtraction from left to right. Choose the correct answer from four options. Select a mode: Easy, Normal, Hard, or Pro. Solve 15 questions to advance to the next level. Harder modes give more XP.
Controls
Enter or select the value of the expression.
How to Play
- Resolve anything inside brackets first.
- Handle powers and roots next.
- Work division and multiplication left to right.
- Finish with addition and subtraction.
Tips & Tricks
Division and multiplication rank equally — do them left to right. Treating multiplication as first is the single most common error here.
Frequently Asked Questions
Which convention does it use?
BODMAS and PEMDAS, which describe the same ordering with different letters.
Why are the numbers so small?
Because the puzzle is the ordering, not the arithmetic. Larger numbers would test calculation instead of precedence.
