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






2. A quantity that does not vary






3. 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






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






5. A quantity that does not vary






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






7. 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






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






9. The reciprocal of a number.






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






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






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






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






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






16. 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)






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






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






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






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






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






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






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






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






26. 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.






27. (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.






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






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






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






31. Same shape - but different size






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






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






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






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






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






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. Numeric value that does not change






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






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






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






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






43. 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.






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