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 mathematical phrase involving one or more terms and operations






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






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






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






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






6. 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






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






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






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






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






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






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. Letter that represents a number; variable amounts may change






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






15. (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.






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






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






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






19. Numeric value that does not change






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






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






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






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






24. 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.






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






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






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






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






29. 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






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






31. Numeric value that does not change






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






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






34. A quantity that does not vary






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






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






37. 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






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






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






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






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






42. 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.






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






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






45. 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






46. 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)






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






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






49. Same shape - but different size






50. 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
