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. 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






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






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






4. 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).






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






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






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






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






9. 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.






10. 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






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






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






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






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






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. A function whose graph is a straight line.






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






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






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






20. 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






21. 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






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






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






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






25. 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






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






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






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






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






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






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






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






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






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






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 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.






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






38. (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.






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






40. The reciprocal of a number.






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. Numeric value that does not change






43. 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






44. 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.
