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






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






4. 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






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






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






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






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






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






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






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






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






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






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






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






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






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. 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)






19. Numeric value that does not change






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






21. Statement that two fractions or ratios are equal






22. A function whose graph is a straight line.






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






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






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






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






27. A quantity that does not vary






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






29. 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).






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






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






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






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






34. A function whose graph is a straight line.






35. 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






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






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






38. 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.






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






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






41. 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.






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

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






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






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






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