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. Same shape - but different size






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






3. 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






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






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






6. 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).






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






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






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






10. 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






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






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






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






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






15. 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.






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






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






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






19. A quantity that does not vary






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. 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






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






36. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






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






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






46. The reciprocal of a number.






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






48. 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






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






50. 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).
