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. Add up the digits; if the sum is a multiple of 3 the number is divisible by 3






2. A set of operators - numbers - variables and grouping symbols; no equal sign






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






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






5. The answer to a multiplication problem






6. Reducing fractions






7. Number divisible by 2






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






9. Multiplying decimals






10. The largest number in a group of numbers






11. Reciprocal of number






12. Standard deviation: greater if...






13. Comparing positive fractions






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






15. Comparing decimal fractions






16. A number that results from multiplying a factor by itself






17. The answer to an addition problem






18. Two factors together that are multiplied to equal a larger number.






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. A number made up of a whole number and a fraction






21. Simplifying complex fractions: two methods






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






23. Percent decrease






24. A comparison of 2 numbers; one form is a fraction






25. Number divisible by 6






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






27. Average value






28. An equation showing 2 ratios are equal






29. Median






30. Multiple-event probability






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






32. Two numbers or expressions that mean the same thing - E.g. 2/3=4/6






33. Adding/subtracting decimals






34. Relationship in which a number is smaller than another






35. 8x8=64 What is 64?






36. Average A per B






37. 1/5 + 1/4=4/20 +5/20 and 20 is the...






38. 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)






39. 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.
