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






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. A function whose graph is a straight line.






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






5. The reciprocal of a number.






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






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






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






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






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






11. 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.






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






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






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






15. A quantity that does not vary






16. Same shape - but different size






17. 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.






18. The reciprocal of a number.






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






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






21. 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






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






23. (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.






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






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






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






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






28. 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






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






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






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






32. 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.






33. A quantity that does not vary






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






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






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






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






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






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






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






41. 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)






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






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






44. 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.






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






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






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






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






49. Statement that two fractions or ratios are equal






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