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






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






4. A quantity that does not vary






5. The reciprocal of a number.






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






7. Numeric value that does not change






8. 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.






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






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






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






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






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






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






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






16. Statement that two fractions or ratios are equal






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






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






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






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






21. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






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






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






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






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






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






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






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






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






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






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






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






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






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






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 symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






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






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






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






40. Statement that two fractions or ratios are equal






41. Same shape - but different size






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






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






44. 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






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. 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






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






48. 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).






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






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