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. (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.






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






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






4. 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






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






6. Statement that two fractions or ratios are equal






7. 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






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






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






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






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






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






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






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






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






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






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






18. 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






19. 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






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






21. A quantity that does not vary






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






23. 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






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






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






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






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






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






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






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






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






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






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






34. Same shape - but different size






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






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






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






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






39. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






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






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






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






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