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.

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






3. Simplifying complex fractions: two methods






4. A number with more than two factors






5. Mode






6. Adding/subtracting fractions






7. Percent x whole






8. 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)






9. A value that does not change; any number






10. Percent increase






11. The smallest number in a group of numbers

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






14. Reducing fractions






15. How much a number is worth






16. Absolute value of number






17. 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.






18. The smallest number that is a multiple of both numbers. (the LCM of 15 and 6 is 30)

25. Rational numbers that expressed in decimal format that have fixed number of digits. 1.5 etc.

42. Able to be divided evenly (without a remainder)






43. 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)
