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. 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






2. Number divisible by 6






3. Simplifying complex fractions: two methods






4. Reducing fractions






5. To change a percent to a decimal






6. Number divisible by 4






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






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)=






9. How much a number is worth






10. Properties of numbers btw -1 and 1






11. To find the answer for; solve






12. Answer to a multiplication problem






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






14. Natural Numbers - Whole Numbers - Integers - Rational Numbers






15. 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)






16. New whole






17. Number divisible by 9






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






19. A fraction whose numerator is greater than its denominator






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






21. Mode






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






23. A number written in expanded form with the place values written in exponential form - E.g. 2432=2000+400+30+2






24. Multiple-event probability






25. Median






26. Absolute value of number






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






28. Properties of 0






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






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






31. When a number is larger than the other number. Example 65 > 56






32. 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.






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






34. Standard deviation: greater if...






35. Multiplying fractions






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