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






2. 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.






3. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






11. Statement that two fractions or ratios are equal






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






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






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






15. Same shape - but different size






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






17. 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






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






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






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






21. (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.






22. 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






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






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






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






26. A quantity that does not vary






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






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






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






30. 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






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






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






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






34. 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






35. 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)






36. 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






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






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






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






40. The reciprocal of a number.






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. 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.






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






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






45. Numeric value that does not change






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






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






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






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






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