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






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






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






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






5. A function whose graph is a straight line.






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






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






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






9. A quantity that does not vary






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






11. 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






12. A function whose graph is a straight line.






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






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






15. 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






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






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






18. (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.






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






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






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






22. 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.






23. 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






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






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






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






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






28. 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






29. Numeric value that does not change






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






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






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






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






34. (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.






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






36. A quantity that does not vary






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






38. 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






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






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






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






42. Same shape - but different size






43. Numeric value that does not change






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






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






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






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






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






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






50. 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.
