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 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






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






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






4. A quantity that does not vary






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






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






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






8. 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)






9. 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






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






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






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






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






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






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






17. (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.






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






19. Any of the numbers (or symbols) that form a product when multiplied together; 3 is a factor of 9






20. The number obtained by division; the ratio of two quantities to be divided; the answer to a division problem






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






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






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






24. A quantity that does not vary






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






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






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






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






29. Numeric value that does not change






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






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






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






33. 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).






34. The reciprocal of a number.






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. 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






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






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






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






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






42. A function whose graph is a straight line.






43. 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)






44. Same shape - but different size






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






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






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






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






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






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