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. The reciprocal of a number.






3. 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






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






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






6. 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






7. Statement that two fractions or ratios are equal






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






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






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






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






12. (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.






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






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






15. (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.






16. 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






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






18. Same shape - but different size






19. 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






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






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






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






23. 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)






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






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






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






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






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






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






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






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






32. 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)






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






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






35. A quantity that does not vary






36. Statement that two fractions or ratios are equal






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






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






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






40. The reciprocal of a number.






41. 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






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






43. 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






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






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






46. A function whose graph is a straight line.






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






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






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






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