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






2. 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.






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






4. 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






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






6. An ordered list or numbers; example: 2 -4 -6 -8 -10...






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






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






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






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






11. 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.






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






13. 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).






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






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






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






17. 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






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






19. A quantity that does not vary






20. Numeric value that does not change






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






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






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






24. 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






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






26. A quantity that does not vary






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






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






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






30. Same shape - but different size






31. Statement that two fractions or ratios are equal






32. 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






33. 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






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






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






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






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






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






39. A decimal number that ends or terminates; example: 6.75






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






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






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






43. (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.






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






45. A function whose graph is a straight line.






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






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






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






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






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