[itex]Q=\sum^3_{i=1}[\frac{1}{2}B_i + I_{3,i}][/itex]

I have to apply this to the proton wave function which is the same as you can see in equation (3.20) here: https://www.google.es/url?sa=t&rct=...mYGwBQ&usg=AFQjCNFeF1HkxpOSTjbWuly9_EJcuTEWeQ

I have only the formula for the first equal. If I apply it because B number is the same for all of them this contribution is 0 and applying the isospin I get also 0 so I have that <p|Q|p>=0 which I assume it's wrong because Q=1. What do I do wrong?

Also, in this formula (3.20) how do they get the second equal? I mean the sum of this terms. I suppose all is about transpose operator but I'm getting quite confused with this.
