pretax dollars box 14

So My W2 has the same amounts listed in box 1, 3 and 5.    Box 14 says pretax and an amount.   Shouldn't the amount in box 14 pretax be deducted from my Box 1 amount?  If the answer would be box 1 would be the amount minus the pretax amount in box 14 then why is box 3 and 5 the same exact amount as box 1?
