How to add math to Steemit Posts

😵
Use unicode. The above weird face is unicode 128565 and I added it by typing &#128565 ; but here I added a space between the unicode and the semicolon so that you could see the format.

A super easy way to do this is to go here:
http://math.typeit.org/
And then enter the math and copy/paste it right into steemit.

∀∃⇒ηΦ¼∈√765→η∈ℂ
∑α

Compare:

∀(x, y ∈ A ∪ B; x ≠ y) x² − y² ≥ 0

For all (x, y :- A u B; x != y) x^2 - y^2 >= 0
