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. Number divisible by 9






2. To drop a percent






3. Natural Numbers - Whole Numbers - Integers - Rational Numbers






4. Standard deviation: greater if...






5. Comparing decimal fractions






6. A letter that represents a value that may change






7. Number divisible by 4






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






9. The largest number in a group of numbers






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






11. Reciprocal of number






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






13. Absolute value of number






14. The answer to an addition problem






15. Number divisible by 2






16. The answer to a multiplication problem






17. 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?






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






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






20. A shortcut for writing repeated multiplication






21. The bottom number in a fraction; tells how many parts a whole is divided into OR how many parts in a group - E.g. 2/4 and what position is the 4?






22. Answer to a division problem






23. New whole






24. Simplifying complex fractions: two methods






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






26. A property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac - or 7x (4+1)=






27. Average A per B






28. odd + odd






29. How much a number is worth






30. 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.






31. A fraction whose numerator is greater than its denominator






32. Adding/subtracting fractions






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






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






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






36. 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






37. A fraction out of 100 - %






38. Not identical or equivalent to






39. Adding/subtracting decimals






40. In multiplication or addition - the order of two numbers may be switched around and the answer is the same. Ex: a+b = b+a. or (1x2) x 3=1x (2x3)






41. Number divisible by 6






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






43. A line for representing and graphing numbers. Each point on the line corresponds to a number.






44. To make a percent






45. 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)






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






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






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