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 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.






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






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






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






5. Statement that two fractions or ratios are equal






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






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






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






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






10. 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






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






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






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






14. 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).






15. 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






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






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






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






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






20. (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.






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






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






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






24. 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






25. A function whose graph is a straight line.






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






27. The reciprocal of a number.






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






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






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






31. A quantity that does not vary






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






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






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






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






36. (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.






37. Numeric value that does not change






38. 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)






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






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






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






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






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






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






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






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






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






48. Numeric value that does not change






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






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