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






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






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






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






5. A quantity that does not vary






6. 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






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






8. 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






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






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






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






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






13. 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).






14. 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






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






16. The reciprocal of a number.






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






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






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






20. Same shape - but different size






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






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






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






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






25. 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.






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






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






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






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






30. (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.






31. 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)






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






33. 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






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






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






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






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 reciprocal of a number.






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






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






41. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.






42. Same shape - but different size






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






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






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






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






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






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






49. A quantity that does not vary






50. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.
