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.
1. The smallest number in a group of numbers






2. The greatest whole number that is a factor of two or more nonzero whole numbers






3. The value of a digit based on its position within a number - e.g. 2 -432 The position of the numbers






4. The answer to a subtraction problem






5. Average value






6. Able to be divided evenly (without a remainder)






7. Absolute value of number






8. A fraction out of 100 - %






9. Number divisible by 4






10. A number written in expanded form with the place values written in exponential form - E.g. 2432=2000+400+30+2






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






12. The answer to an addition problem






13. Median






14. Any whole number that ends with 0 - 2 - 4 - 6 - or 8 - any whole number that can be divided by 2






15. Two expressions that are set equal to each other; a number sentence with an equal sign






16. Be identical or equivalent to






17. To make a percent






18. Numbers that are easy to compute mentally - E.g. 34 / 5 is close to 35 / 5






19. 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






20. The property which allows you to add a number's opposite to it and always get 0 - The relationship of addition to subtraction or multiplication to division






21. To change a percent to a decimal






22. Number divisible by 2






23. Simplifying complex fractions: two methods






24. 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)






25. 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.
