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






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






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






4. 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.






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






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






7. A quantity that does not vary






8. 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)






9. Numeric value that does not change






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






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






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






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






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 decimal number that ends or terminates; example: 6.75






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






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






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






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






20. A quantity that does not vary






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






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






23. Numeric value that does not change






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






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






26. Statement that two fractions or ratios are equal






27. 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






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






29. 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






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






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






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






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






34. 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






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






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






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






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






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






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






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






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






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






44. 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






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






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






47. 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)






48. 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).






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






50. 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.
