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. Numeric value that does not change






2. 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)






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






4. 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






5. 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






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






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






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






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






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






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






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






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






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






15. Same shape - but different size






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






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






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






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






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






21. 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).






22. The reciprocal of a number.






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






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






25. Numeric value that does not change






26. 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






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






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






29. 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.






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






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






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






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






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






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






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






37. 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






38. 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.






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






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






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






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






43. 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






44. Same shape - but different size






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






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






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






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






49. 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)
