Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.

2. 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

4. Number divisible by 9






5. Probability






6. Adding/subtracting fractions






7. New whole






8. Not identical or equivalent to






9. 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)






10. Simplifying complex fractions: two methods






11. Dividing decimals






12. Multiplying decimals

16. To make a percent






17. 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)






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






19. Adding/subtracting decimals






20. 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.






21. Number divisible by 3






22. Absolute value of number






23. 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?






24. Relationship in which a number is smaller than another






25. Multiplying fractions






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

32. Average A per B






33. Number divisible by 5






34. Percent x whole

36. Median






37. Reducing fractions






38. A letter that represents a value that may change






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

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






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






43. 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






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






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






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






47. Percent increase






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






49. A shortcut for writing repeated multiplication






50. PEMDAS - Parentheses - Exponents - Multiplication & Division (L to R) - Addition & Subtraction (L to R)
