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






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






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






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






5. 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






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






7. Numeric value that does not change






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






9. Same shape - but different size






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






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






12. Same shape - but different size






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






14. A quantity that does not vary






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






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






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






18. A function whose graph is a straight line.






19. A function whose graph is a straight line.






20. Statement that two fractions or ratios are equal






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






22. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






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






24. 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






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






26. 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.






27. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction






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






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






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






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






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






33. (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.






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






35. 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






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






37. A quantity that does not vary






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






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






41. (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.






42. 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).






43. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






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






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






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






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






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






49. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction
