 Feb 25, 2011 MATH-SUBSETS Using Set Builder Notation by: Staff The question: by AMBER (OHIO)A = {x | x ¡Ê N and x < 6}B = {x | x ¡Ê N and 1 ¡Ü x ¡Ü 5}The answer:To type the following symbols on your keyboard, hold down the ALT key, type the code, then release the ALT key:⊂, subset, 8834⊃, superset, 8835∈, element of a set, 8712∩, intersection, 8745∪, union, 8746Ø, null set, 0216≥, greater than or equal to, 8805 ≤, less than or equal to, 8804Note: N = Set of all Natural Numbers = {1,2,3,4,5,...}(some authors also include 0 as part of the set of all Natural Numbers) Some of the symbols you submitted did not display properly, but I think this is what you probably meant:A = {x | x ∈ N and x < 6}the set of all x, where x is a subset of N, and x is less than 6B = {x | x ∈ N and 1 ≤ x ≤ 5}the set of all x, where x is a subset of N, and x is greater than or equal to 1, and less than or equal to 5You didn't say what problem you are trying to solve.For your information, both sets are equal:A = {x | x ∈ N and x < 6} = {1,2,3,4,5}B = {x | x ∈ N and 1 ≤ x ≤ 5} = {1,2,3,4,5}Thanks for writing.Staff www.solving-math-problems.com
