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






2. 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






3. 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).






4. Numeric value that does not change






5. Same shape - but different size






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






7. 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.






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 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).






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






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






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






14. The reciprocal of a number.






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






16. 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






17. 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






18. 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






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






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






21. (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.






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






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






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






25. The reciprocal of a number.






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






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






28. 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






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






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






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






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






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






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






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






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






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






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






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






40. Statement that two fractions or ratios are equal






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






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






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






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






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






46. 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






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






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