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






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






3. (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.






4. Same shape - but different size






5. Statement that two fractions or ratios are equal






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






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






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






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






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






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






12. 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).






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






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






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






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






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






18. A function whose graph is a straight line.






19. 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






20. 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






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






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






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






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






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






26. 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).






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






28. 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






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






30. The reciprocal of a number.






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






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






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






34. 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






35. (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.






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






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






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






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






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






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






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






45. 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.






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






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






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






49. Numeric value that does not change






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