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






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






3. 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






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






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






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






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






8. 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






9. Same shape - but different size






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






11. 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






12. A function whose graph is a straight line.






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






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






15. 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)






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






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






18. 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






19. 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)






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






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






22. 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






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






24. 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).






25. A quantity that does not vary






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






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






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






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






30. Statement that two fractions or ratios are equal






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






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






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






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






35. Statement that two fractions or ratios are equal






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






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






38. 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






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






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






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






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






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






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






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






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






47. (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.






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