To clear this up, lets look at an example.  Let set \(A\)=\(\left\{10,11,12\right\}\) and set \(B=\left\{11,12,13,14\right\}\).

contenteditable="false">\(undefined\) (Notice contenteditable="false" data-equation="A\cup B=\left\{10,11,12,13,14\right\}">\(A\cup B=\left\{10,11,12,13,14\right\}\)(Notice  each element is only listed once even though each set shares common elements)
contenteditable="false">\(undefined\) (Notice contenteditable="false" data-equation="A\cap B=\left\{11,12\right\}">\(A\cap B=\left\{11,12\right\}\)(Notice  both sets share these elements)
 elements)
  class="ltx_Math" contenteditable="false" data-equation="\left|A\right|=3">\(\left|A\right|=3\) and contenteditable="false">\(undefined\)
 contenteditable="false" data-equation="\left|B\right|=4">\(\left|B\right|=4\)
