Middle Grade Math And Basic Algebra

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






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






3. A function whose graph is a straight line.






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






5. The reciprocal of a number.






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






7. Statement that two fractions or ratios are equal






8. The point where the x-axis and y-axis intersect on the coordinate plane; (0 - 0).






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






10. Same shape - but different size






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






12. For any number a and b - a + b = b + a






13. 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






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






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






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






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






18. (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.






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






20. Same shape - but different size






21. Specific form of representing ratios - examples - a to b or 2 to 3






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






23. Numeric value that does not change






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






25. 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






26. 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).






27. Numeric value that does not change






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






29. (mathematics) one of a pair of numbers whose sum is zero






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






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






32. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.






33. An expression that contains only numbers and operations (2 3) + 1






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






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






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






37. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






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






39. A quantity that does not vary






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






41. 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.






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






43. Specific form of representing ratios - examples - a to b or 2 to 3






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






45. The point where the x-axis and y-axis intersect on the coordinate plane; (0 - 0).






46. (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.






47. (mathematics) one of a pair of numbers whose sum is zero






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






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






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