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






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






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






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






5. (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.






6. The reciprocal of a number.






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






8. A quantity that does not vary






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






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






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






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






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






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






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






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






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






18. Statement that two fractions or ratios are equal






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






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






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






22. Same shape - but different size






23. 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






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






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






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






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






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






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






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






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






32. Numeric value that does not change






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






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






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






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






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






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






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






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






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






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






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






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






46. Numeric value that does not change






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






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






49. 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).






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