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






2. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






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






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






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






13. Numeric value that does not change






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






15. A quantity that does not vary






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






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






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






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






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






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






22. 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.






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






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






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






26. Same shape - but different size






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






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






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






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






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






32. 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






33. The reciprocal of a number.






34. (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.






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






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






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






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






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






40. 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.






41. 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).






42. A function whose graph is a straight line.






43. 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






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






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






46. 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.






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






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






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






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