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. Math phrase that uses variables - numbers and operation symbols






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






3. (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.






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






5. 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






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






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






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






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






10. Statement that two fractions or ratios are equal






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






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






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






14. Same shape - but different size






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






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






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






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






19. Same shape - but different size






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






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






22. The reciprocal of a number.






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






24. 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






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






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






27. A function whose graph is a straight line.






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






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






30. 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






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






32. 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






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






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






35. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






49. 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).






50. 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
