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






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






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






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






5. 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






6. The reciprocal of a number.






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






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






9. Statement that two fractions or ratios are equal






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






11. Numeric value that does not change






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






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






14. The reciprocal of a number.






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






16. 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






17. 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






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






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






20. 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.






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






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






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






24. (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.






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






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






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






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






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






30. 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)






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






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






33. Statement that two fractions or ratios are equal






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






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






36. Same shape - but different size






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






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






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






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






41. A quantity that does not vary






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






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






44. 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.






45. 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).






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






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






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






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






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