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






2. Same shape - but different size






3. 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






4. Same shape - but different size






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






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






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






8. The reciprocal of a number.






9. 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






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






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






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






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






14. 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






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






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






17. 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






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






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






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






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






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






24. 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.






25. 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






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






27. 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)






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






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






30. Statement that two fractions or ratios are equal






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






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






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






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






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






36. The reciprocal of a number.






37. Statement that two fractions or ratios are equal






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






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






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






41. 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






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






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






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






45. Numeric value that does not change






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






47. Math phrase that uses variables - numbers and operation symbols






48. (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.






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






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