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






2. 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






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






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






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






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






7. Statement that two fractions or ratios are equal






8. 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






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. The reciprocal of a number.






11. 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)






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






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






14. 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






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






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






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






19. Numeric value that does not change






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






21. 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






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






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






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






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






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






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 function whose graph is a straight line.






29. 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.






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






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






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






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






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






35. Statement that two fractions or ratios are equal






36. 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






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






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






40. (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.
