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 reciprocal of a number.






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






3. 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).






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






5. 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.






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






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






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






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






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






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






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






13. A quantity that does not vary






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






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






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






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






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






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






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






22. Statement that two fractions or ratios are equal






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






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






25. A function whose graph is a straight line.






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






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






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






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






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






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






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






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






34. Same shape - but different size






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






36. Numeric value that does not change






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






38. 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).






39. 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






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






41. Numeric value that does not change






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






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






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






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






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






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






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






49. The reciprocal of a number.






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