Subjects : math, algebra
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. Numeric value that does not change






2. Numeric value that does not change






3. The number that indicates how many times the base is used as a factor






4. The product of a quantity by an integer; example 24 is a multiple of 3 and 8






5. Letter that represents a number; variable amounts may change






6. A pair of numbers that can be used to locate a point on a coordinate plane.






7. Same shape - but different size






8. A quantity that does not vary






9. The ratio between the size of something and a representation of it






10. A diagram of an object in which the dimensions are in proportion to the actual dimensions of the object.






11. A number multiplied by a variable in an algebraic expression; a constant number that serves as a measure of some property or characteristic






12. The reciprocal of a number.






13. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






14. The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants; A coordinate system formed by the intersection of a horizontal number line - called the x-axis - and a vertical number line - called the y-axi






15. A mathematical phrase involving one or more terms and operations






16. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 9.






17. A fraction in which the numerator is greater than or equal to the denominator; examples: 5/5 or 7/4






18. Statement that two fractions or ratios are equal






19. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






20. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






21. 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; ex: 4(3 + 8)






22. A decimal in which one or more digits repeat infinitely; The repeating portion of the decimal is shown with a short line drawn over the repeating numbers.






23. Expressions that contain the same variables to the same power






24. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






25. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 9.






26. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






27. 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; ex: 4(3 + 8)






28. An input-output relationship that has exactly one output for each input; An equation written with two variables where only one output exists for each input; example: y = 2x +1






29. A comparison of two quantities - may be directly represented by numbers and or variables






30. A pair of numbers that can be used to locate a point on a coordinate plane.






31. Specific form of representing ratios - examples - a:b or 2:3






32. A mathematical phrase involving one or more terms and operations






33. Math phrase that uses variables - numbers and operation symbols






34. All rational or irrational numbers; real numbers can be represented on the real number line






35. Fractions that name the same amount or part - 1/2 and 2/4 are equivalent fractions






36. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is






37. Changing the grouping of terms will not change the sum - (a + b) + c = a + (b + c); ex: (5+3) + 1 = 5 + (3 + 1)






38. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






39. A quantity obtained by multiplication; the answer to a multiplication problem






40. States that changing grouping of factors does not change the product. (ab)c = a(bc); ex: (2 6) 7 = 2 (6 7)






41. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






42. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






43. The distance from zero to the real number on a number line.






44. A real number that cannot be expressed as a rational number






45. A comparison of two quantities - may be directly represented by numbers and or variables






46. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction






47. Expressions that contain the same variables to the same power






48. A method of measurement that uses formulas - similar figures - and/or proportions.






49. An equation whose solutions form a straight line on a coordinate plane; example: y = 3x - 1






50. (mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; a fraction that has been flipped. The reciprocal of 3/4 is 4/3.
