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 decimal number that ends or terminates; example: 6.75






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. 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






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






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






7. Same shape - but different size






8. 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






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






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






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






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






14. (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.






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






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






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






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. 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






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






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






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






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






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






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






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






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






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






29. 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






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






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






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






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






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






35. Same shape - but different size






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






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






38. 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).






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






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






41. Statement that two fractions or ratios are equal






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






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






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






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






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






47. 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.






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






49. (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.






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