Simple Mathematical equation confusion riddle

One of your friends comes to you with a simple mathematical equation.
25 – 55 + (85 + 65) = ?
You solve the equation to get 120 as the result and tells him that it was as easy as eating a pie.
To this, your friend reverts, “You won’t believe that the actual answer to this question is 5!

You are left dumbfounded at this statement. How can this be true?

    25 – 55 + (85 + 65) =120
    5! (5 factorial that is 5*4*3*2*1)=120
    So both are equal

    Possible ONLY IF the “revert” is in writing. 🙂
