**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.

**4. Number divisible by 2**

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

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

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

**8. To find a number that is close to an exact answer - E.g. 23+24 is around 50**

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

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

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

**12. Percent x whole**

**13. When you add 0 to a number - or mulltiply a number by 1 - the result is the same number - e.g. Identity Property of Multiplication: 21x1=1x21=21 or 300x 1 = 300**

**14. Number divisible by 3**

**15. A number made up of a whole number and a fraction**

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

**17. Probability**

**18. Relationship in which a number is smaller than another**

**19. Number divisible by 6**

**20. 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)**

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

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

**23. Multiplying fractions**

**24. Reciprocal of number**

**25. To make a percent**

**26. Answer to a multiplication problem**

**27. The bottom number in a fraction; tells how many parts a whole is divided into OR how many parts in a group - E.g. 2/4 and what position is the 4?**

**28. 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**

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

**30. Number divisible by 5**

**31. 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?**

**32. Properties of 1 and -1**

**33. Average A per B**

**34. 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.**

**35. Number divisible by 4**
