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






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






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






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






5. 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.






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






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






8. Same shape - but different size






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






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






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






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






14. (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.






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






17. 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.






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






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






20. 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






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






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. 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






25. The reciprocal of a number.






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






27. 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.






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






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






30. Numeric value that does not change






31. Statement that two fractions or ratios are equal






32. 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).






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






34. The reciprocal of a number.






35. (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.






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






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






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






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






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






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






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






43. 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).






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






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






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






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






48. 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






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






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