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 ratio between the size of something and a representation of it






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






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






4. Same shape - but different size






5. A quantity that does not vary






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






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






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






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






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






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






12. 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






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






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






15. 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






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






17. 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






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






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






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






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






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






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






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






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






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






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






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






30. The reciprocal of a number.






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






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






33. 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






34. 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).






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






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






37. Statement that two fractions or ratios are equal






38. 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






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






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






41. A function whose graph is a straight line.






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






43. 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






44. 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.






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






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






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