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. (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.






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






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






4. 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






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






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






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






8. A function whose graph is a straight line.






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






10. 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.






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






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






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






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






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






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






17. The reciprocal of a number.






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






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






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






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






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






23. 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






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






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






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






27. Statement that two fractions or ratios are equal






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






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






30. 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)






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






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






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






34. 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.






35. 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






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






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






38. A quantity that does not vary






39. Same shape - but different size






40. 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.






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






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






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






44. Numeric value that does not change






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






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






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






48. A function whose graph is a straight line.






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






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