Fraction Addition & Subtraction
Practice fraction addition and subtraction with a free, browser-based math game. Includes step-by-step strategy, common mistakes, and classroom tips.
MathOrder of Operations
Arithmetic has a fixed order: multiplication before addition. So 3 + 4 × 2 is 11, not 14. Below: the rule, and why the left-to-right answer always appears among the options.

MathWhat you are actually practicing
Arithmetic has a fixed order: multiplication before addition, unless brackets say otherwise. So 3 + 4 × 2 is 11, not 14. The rule exists to make an expression mean exactly one thing — and failing to apply it is the most common arithmetic slip in adult life, spreadsheets included.
This game drills two-operator expressions where the order genuinely changes the answer.
How the game works
You are shown an expression with two operations, and four possible values. Pick the correct one. A wrong pick reveals the answer immediately.
Easy puts the multiplication second, which is where the rule bites. Medium puts it first. Hard mixes addition, subtraction and multiplication with larger numbers.
The rule worth knowing
Multiplication before addition and subtraction. 3 + 4 × 2 = 3 + 8 = 11.
Left to right among equal operations. 10 - 3 - 2 = 5, not 9.
Strategies that actually raise your score
Mark the multiplication first. Circle the × pair mentally, resolve it, then come back to the rest. One pass, no ambiguity.
Expect the wrong option to be on screen. The result of simply working left to right is deliberately included as a distractor. If your answer matches a value you could only get by ignoring the order rule, check again.
Resolve the product, then add or subtract once. 4 × 2 = 8, then 3 + 8 = 11. Two steps is faster than it feels, and it removes the ordering question entirely.
Use the size as a shortcut. With 3 + 4 × 2 the answer must be at least 8, so 7 and anything below is out before you finish calculating.
