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






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






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






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






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






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






8. 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.






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






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






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






12. A quantity that does not vary






13. 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






14. 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.






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






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






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






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






19. 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)






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






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






22. 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).






23. 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)






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






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






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






27. 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






28. 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






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






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






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






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






33. 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.






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






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






36. A function whose graph is a straight line.






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






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






39. A quantity that does not vary






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






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






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






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






44. Statement that two fractions or ratios are equal






45. Statement that two fractions or ratios are equal






46. 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






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






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