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






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






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






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






5. A quantity that does not vary






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






7. Same shape - but different size






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. 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.






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






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






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






13. 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.






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






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






16. The reciprocal of a number.






17. 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






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






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






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






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






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






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






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






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






26. 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






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






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






29. A function whose graph is a straight line.






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






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






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






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






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






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






36. (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.






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






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






39. 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






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






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






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






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






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






45. 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






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






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






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






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






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