**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. Not identical or equivalent to**

**3. In 4x4=16 - what is 4?**

**4. New whole**

**5. Number divisible by 6**

**6. To change a percent to a decimal**

**7. 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**

**8. Standard deviation: greater if...**

**9. A number with more than two factors**

**10. Average A per B**

**11. Simplifying complex fractions: two methods**

**12. The answer to an addition problem**

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

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

**15. 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)**

**16. Number divisible by 9**

**17. odd + odd**

**18. Natural Numbers - Whole Numbers - Integers - Rational Numbers**

**19. To find the answer for; solve**

**25. The answer to a subtraction problem**

**26. Dividing decimals**

**27. Absolute value of number**

**28. 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.**

**29. 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)**

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

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

**34. Properties of numbers btw -1 and 1**

**35. The answer to a multiplication problem**

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

**37. Percent decrease**

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