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.

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






8. 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)=

13. odd + odd






14. 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)

21. 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






22. Multiplying fractions






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

35. To make a percent






36. Comparing decimal fractions






37. The difference between the greatest and the least numbers in a set of data.






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






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






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. A shortcut for writing repeated multiplication






42. A fraction out of 100 - %






43. The answer to a subtraction problem

48. Adding/subtracting fractions






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






50. 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.
