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






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






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






4. 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






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






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






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






8. The reciprocal of a number.






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






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






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. Same shape - but different size






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






14. 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)






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






16. 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).






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






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






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






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






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






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






23. 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






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






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






26. Numeric value that does not change






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






28. 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






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






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






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






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






33. 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.






34. 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






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






36. A function whose graph is a straight line.






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






38. (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.






39. 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






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






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






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






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






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