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






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






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






4. 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






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






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






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






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






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






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






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






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






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






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






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






16. 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).






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






18. 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.






19. 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






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






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






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






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






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






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






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






27. 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.






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






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






31. A quantity that does not vary






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






33. 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)






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






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






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






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






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






39. 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






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






41. 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
