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. Math phrase that uses variables - numbers and operation symbols






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






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






4. Numeric value that does not change






5. 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






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






7. A function whose graph is a straight line.






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






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






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






11. 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






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






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






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






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






16. A function whose graph is a straight line.






17. Numeric value that does not change






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






19. 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.






20. The reciprocal of a number.






21. The reciprocal of a number.






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






23. 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






24. 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.






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






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






27. 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)






28. 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






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






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






31. 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).






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






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






34. (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.






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






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






37. (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.






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






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






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






41. 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






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






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






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






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






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






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






48. A quantity that does not vary






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






50. 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.
