Find the Operator Game

Practice math skills by identifying the correct operator in equations

★★★★★Beginner

How to Play

  1. 1An equation with a missing operator will appear
  2. 2Two numbers and a result are shown
  3. 3Click the operator (+, −, ×, ÷) that makes the equation true
  4. 4Improve your mathematical reasoning and operator recognition
🧠

Reasoning backwards from a result to its operation trains arithmetic flexibility — thinking about numbers in terms of relationships rather than procedures. This reversal is more demanding than forward calculation and builds deeper number sense.

About This Game

Find the Operator presents a complete equation with one element missing: the operator. You must determine whether + , − , × , or ÷ makes the equation true. This trains arithmetic flexibility — the ability to think about numbers in terms of their relationships rather than just their values.

Where standard arithmetic games ask you to compute a result, this game asks you to reason backwards: given two numbers and a result, which operation connects them? This reversal is more cognitively demanding because it requires testing multiple hypotheses and eliminating candidates, rather than applying a single known procedure.

Regular play develops comfort with the four basic operations across a wide range of number combinations, and builds the intuition to recognise at a glance whether a numerical relationship is additive, multiplicative, or neither.

Goal

Choose the operator (+, −, ×, or ÷) that makes the equation true. You reason backwards from numbers and result to the operation.

Difficulty

Equations use different operations and number sizes. Levels add more problems per round and tighter time pressure.
