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






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






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






4. 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






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






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






7. (mathematics) one of a pair of numbers whose sum is zero






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






9. (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.






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






11. 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).






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






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






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






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






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






17. A function whose graph is a straight line.






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 reciprocal of a number.






21. Same shape - but different size






22. Statement that two fractions or ratios are equal






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






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






25. 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).






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






27. 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






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






30. 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)






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






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






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






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






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






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






37. A quantity that does not vary






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






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






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






41. Statement that two fractions or ratios are equal






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






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






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






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






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






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






48. 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.
