Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

3. In 4x4=16 - what is 4?






4. New whole






5. Number divisible by 6






6. To change a percent to a decimal






7. Cannot be expressed in the form a/b. Include square roots of whole numbers that are not perfect squares and non terminating decimals that do not repeat. pi

10. Average A per B






11. Simplifying complex fractions: two methods






12. The answer to an addition problem






13. A number with one or more digits to the right of the decimal point - E.g. .33






14. A number with only two factors - one and itself - E.g. 3 -7 -11 -13 -17 -19...






15. A property of real numbers that states that the sum or product of a set of numbers is the same - regardless of how the numbers are grouped - (a+b)+c=a+(b+c) - e.g. (1+2)+3=1+(2+3)






16. Number divisible by 9






17. odd + odd






18. Natural Numbers - Whole Numbers - Integers - Rational Numbers

27. Absolute value of number






28. Choosing numbers close to the numbers in a problem - and then adjusting the answer to compensate for the numbers chosen - E.g. 23 + 18 and 23+20=43 Since 2 was added to 18 to make 20 - we need to take 2 away from 43.
