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

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

14. Average value

15. Not identical or equivalent to

16. Adding/subtracting decimals

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

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 - %
