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






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






3. Same shape - but different size






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






5. 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






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






7. 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)






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






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






10. Numeric value that does not change






11. 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






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






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






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






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






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






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






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






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






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






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






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






23. 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).






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






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






26. 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)






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






28. 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






29. 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.






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






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






32. Same shape - but different size






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






34. The reciprocal of a number.






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






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






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






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






39. 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






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






42. 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.






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






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






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






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

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






50. The reciprocal of a number.
