To avoid unnecessary googling for set theory symbols I pasted most frequent ones here.

φ(E⊃E) = 1 – φE + φE · φE = 1 – φE + φE
φ(E⊃E) = 1 – φE + φE · φE = 1 – φE + φE
φ(W⇔M) = 1 – | φW – φM |
φ(W⊃M) = 1 – φW + φW · φM

Here’s another interesting repertoire of set theory symbols. Cool diagrams too.
Thanks for the information. Unfortunately it is not possible to copy symbols from that website to use while typing notes 🙁
