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 quantity that does not vary






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






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






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






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






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






7. 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.






8. 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






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






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






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






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






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






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






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






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






17. 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






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






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






20. 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






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






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






23. Numeric value that does not change






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






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






26. 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






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






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






29. (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.






30. 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






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






32. The reciprocal of a number.






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






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






35. 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).






36. A function whose graph is a straight line.






37. 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






38. 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.






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






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






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






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






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






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






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






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






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






48. 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






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






50. The reciprocal of a number.
