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






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






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






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






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






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






7. A quantity that does not vary






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






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






10. (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.






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






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






13. 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)






14. 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






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






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






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






18. 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






19. The reciprocal of a number.






20. 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






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






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






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






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






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






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






27. A function whose graph is a straight line.






28. Numeric value that does not change






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






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






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






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






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






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






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






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






37. 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






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






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






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






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






42. 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






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






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






45. 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






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






47. 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).






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