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






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






3. Same shape - but different size






4. 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






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






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






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






8. (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.






9. 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






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






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






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






13. 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.






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






15. 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






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






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






18. 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).






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






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






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. 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






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






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






25. Numeric value that does not change






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






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






28. A function whose graph is a straight line.






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






30. Statement that two fractions or ratios are equal






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






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






33. (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.






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






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






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






37. 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






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






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






40. 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.






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






42. 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)






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






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






45. 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






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






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






48. Statement that two fractions or ratios are equal






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






50. 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).
