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






3. 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)






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






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






6. 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






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






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






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






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






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






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






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






14. 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).






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






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






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






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






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






20. The reciprocal of a number.






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






22. 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.






23. 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.






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






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






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






27. (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.






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






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






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






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






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






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






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






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






36. 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






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






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






39. Numeric value that does not change






40. 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






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






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






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






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






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






46. A quantity that does not vary






47. 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






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






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






50. 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
