**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**

**37. Average A per B**

**38. The number at the top of a fraction; stands for the parts of a set you are considering - E.g. 3/4 What position is 3?**

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

**43. Dividing fractions**

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

**45. Adding/subtracting decimals**

**46. A letter that represents a value that may change**

**47. To drop a percent**

**48. A shortcut for writing repeated multiplication**
