Hey Could you give me a hint how to explain this example? Need help to prove statement in red frame. Example from book (Topics In Banach Space Integration) by Ye Guoju‏، Schwabik StefanThank you

1) $\cap_{i=1}^{n} A_{i}= A_{1}\setminus \cup_{i=1}^{n}(A_{1}\setminus A_{i})$ 2) $\cap_{i=1}^{\infty} A_{i}= A_{1}\setminus \cup_{i=1}^{\infty}(A_{1}\setminus A_{i})$
