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. 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.






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. A function whose graph is a straight line.






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






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






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






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






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






9. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






17. A quantity that does not vary






18. 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






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






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






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






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






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






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






26. 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.






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






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. Letter that represents a number; variable amounts may change






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






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






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






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






34. A quantity that does not vary






35. Same shape - but different size






36. 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.






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






38. (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.






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






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






41. 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






42. 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)






43. 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).






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






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






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






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