The answer: If an entire set is contained within another set, it is called a SUBSET. For example, suppose set A contains only three numbers: 1, 2, and 3 In set notation: A = {1,2,3} Now suppose set B contains ten numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 In set notation: B = {0,1,2,3,4,5,6,7,8,9} Set B contains more numbers than set A, but ALL OF THE NUMBERS IN SET A are CONTAINED IN SET B A is a SUBSET of B This is written using the ⊂ symbol. (You can type this symbol on your computer by holding down the ALT key, typing 8834, then releasing the ALT key.) A is a SUBSET of B A ⊂ B You can find some other examples of sets, subsets, elements, etc., at: http://www.solving-math-problems.com/math-symbols-subset-proper-1-left.html Thanks for writing.
