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






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






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






5. 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






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






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






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






9. 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






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






11. A function whose graph is a straight line.






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






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






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






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






16. 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






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






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






20. Same shape - but different size






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






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






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






24. 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






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






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






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






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






29. Statement that two fractions or ratios are equal






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






31. 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






32. A quantity that does not vary






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






34. The reciprocal of a number.






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






36. 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).






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






38. 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






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






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






41. A function whose graph is a straight line.






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






43. 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






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






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






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






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






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






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






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