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 real number that cannot be expressed as a rational number






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






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






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






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






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






7. 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






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






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






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






11. 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






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






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






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






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






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






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






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






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






20. 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)






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






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






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






24. Same shape - but different size






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






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






27. Same shape - but different size






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






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






30. The reciprocal of a number.






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






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






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






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






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






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






37. 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).






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






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






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






41. A quantity that does not vary






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






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






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






45. The reciprocal of a number.






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






47. 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
