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 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






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






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






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






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






7. A quantity that does not vary






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






9. 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).






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






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






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






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






14. 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.






15. Statement that two fractions or ratios are equal






16. 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






17. Statement that two fractions or ratios are equal






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






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






20. 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)






21. Same shape - but different size






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






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






24. The reciprocal of a number.






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






27. A function whose graph is a straight line.






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






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






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






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






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






33. The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants; A coordinate system formed by the intersection of a horizontal number line - called the x-axis - and a vertical number line - called the y-axi






34. (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.






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






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






37. 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.






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






39. 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






40. 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






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






42. A quantity that does not vary






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






44. Same shape - but different size






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






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






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






48. 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






49. 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
