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. 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






3. 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






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






5. Statement that two fractions or ratios are equal






6. (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.






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






8. 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)






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






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






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






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






13. 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






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






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






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






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






18. The reciprocal of a number.






19. Numeric value that does not change






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






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






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






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






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






25. 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






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






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






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






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






30. A fraction in which the numerator is greater than or equal to the denominator; examples: 5/5 or 7/4






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






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






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






34. The reciprocal of a number.






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






36. A quantity that does not vary






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






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






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






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






41. 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.






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






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






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






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






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






47. 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).






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






49. 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






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