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






3. 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






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






5. 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






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






7. A function whose graph is a straight line.






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






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






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






11. 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






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






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






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






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






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






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






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






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






20. A quantity that does not vary






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






22. (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.






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






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






25. A function whose graph is a straight line.






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






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






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






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






30. Numeric value that does not change






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






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






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






34. 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.






35. Statement that two fractions or ratios are equal






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






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






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






39. 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






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






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






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






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






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






45. (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.






46. 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






47. 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






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






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