    in other words the question is asking if 6 is an element of the set (1,2,3,4,5,6,7)

    The relation "is an element of", also called set membership, is denoted by the symbol "∈".

    it's true that sign means ' is a element of' and the numbers in the parentheses is called a set as you see 6 is included in th set

    oh hold - sorry it is false because [6] is the 'set 6 ' not 6

    6 is an element of the set but the set {6} is not

    ah okay so if it was 6 by itself it would be true, but since it's 1-7 it makes it false?

    if {6} was an element then the big set might be {1,2,3,4,5, {6}, 7 } then {6} would be a sub set I'm the big set
