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 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






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






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






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






5. A quantity that does not vary






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






7. 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






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






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






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






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






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






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






14. 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






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






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






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






18. 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






19. The reciprocal of a number.






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






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






22. 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).






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






24. Statement that two fractions or ratios are equal






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






26. Same shape - but different size






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






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






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






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






31. Math phrase that uses variables - numbers and operation symbols






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






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






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






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






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






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






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






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






40. 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






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






42. Numeric value that does not change






43. 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






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






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






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






47. 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






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






49. 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.
