GOOD TO KNOW

Common questions

Which operations are included?

Addition and subtraction are used at easy levels; multiplication and division are added at harder levels. Division questions always have whole-number answers.

Does my score measure ability?

No. The score only counts correct answers in the current randomized practice round and is not a test or educational measurement.
