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. 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






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






3. A function whose graph is a straight line.






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






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






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






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






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






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






10. 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.






11. Same shape - but different size






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






13. Numeric value that does not change






14. 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.






15. A quantity that does not vary






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






17. 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






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






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






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






21. The reciprocal of a number.






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






23. The reciprocal of a number.






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






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






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






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






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






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






30. The ratio of dimensions of the new image to those of the original figure






31. Numeric value that does not change






32. 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






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






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






35. (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.






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






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






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






39. 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






40. 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






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






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






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






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






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






46. Specific form of representing ratios - examples - a/b or 2/3 (denominator cannot be zero)






47. 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)






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






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






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