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. Numeric value that does not change






2. 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.






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






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






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






6. 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.






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






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






9. 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).






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






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






12. 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






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






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






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






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






17. 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)






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






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






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






21. Statement that two fractions or ratios are equal






22. Same shape - but different size






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






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






25. 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






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






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






28. 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






29. Same shape - but different size






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






31. 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






32. 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






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






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






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






36. A quantity that does not vary






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






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






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






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






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






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






43. A quantity that does not vary






44. The reciprocal of a number.






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






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






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






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






49. 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).






50. 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)
