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.

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






2. To change a percent to a decimal






3. 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






4. Comparing positive fractions






5. The answer to a multiplication problem






6. A fraction out of 100 - %






7. A number without fractions; an integer- E.g. 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9...






8. When you add 0 to a number - or mulltiply a number by 1 - the result is the same number - e.g. Identity Property of Multiplication: 21x1=1x21=21 or 300x 1 = 300






9. A fraction whose numerator is greater than its denominator






10. Rational numbers in decimal form that have a block of on or more digits that repeat continuously






11. Median






12. The number at the top of a fraction; stands for the parts of a set you are considering - E.g. 3/4 What position is 3?






13. 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






14. Answer to a multiplication problem






15. A number that represents a part of a whole or a group; also means 'divided by' - E.g. 1/2 -3/4.5/6






16. A whole number such as 1 - 3 - 5 and so on that cannot be evenly divisible by 2






17. The expression of a number as a product of prime factors; use a factor tree!






18. New whole

24. Number divisible by 4






25. 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)






26. To drop a percent






27. 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.






28. Any of the symbols used to write numbers (0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9)
