Where did the terms \overline{E \overline{P}} - \overline{\overline{E} P} go?

Hello!

I'm getting muddled with the notation in my notes, in which I have

\overline{(E-\overline{E})(P-\overline{P})}

From which you can get

\overline{EP} - \overline{E} \ \overline{P}I can see where these come from, but not where the

\overline{E \overline{P}} - \overline{\overline{E} P}

terms vanished to?

\overline{EP} - \overline{E} \ \overline{P}

I can see where these come from, but not where the

\overline{E \overline{P}} - \overline{\overline{E} P}

terms vanished to?

\overline{E \overline{P}} = \overline{\overline{E} P} = \overline{E} \ \overline{P}

so they cancel out.

Great thank you!
