**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 to obvious but it re-enforces your understanding as you take the test each time.

**1. 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)=**

**2. The largest number in a group of numbers**

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

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

**5. Answer to a division problem**

**6. Able to be divided evenly (without a remainder)**

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

**8. Multiplying fractions**

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

**10. A number that results from multiplying a factor by itself**

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

**12. How much a number is worth**

**14. Average value**

**15. Not identical or equivalent to**

**18. Answer to a multiplication problem**

**19. Reducing fractions**

**20. To place a fraction in lowest terms**

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

**22. Average A per B**

**23. Median**

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

**25. A value that does not change; any number**

**26. Absolute value of number**

**27. Percent decrease**

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

**29. Number divisible by 5**

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

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

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

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

**34. Number divisible by 3**

**35. 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)**

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

**37. Comparing decimal fractions**

**38. The greatest whole number that is a factor of two or more nonzero whole numbers**

**39. Standard deviation: greater if...**

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

**41. 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.**

**42. A fraction out of 100 - %**
