In my calculus III class, the instuctor sometimes uses a "shorthand", like instead of therefore, he uses three dots (2 on bottom,1 on top) or instead of all, he uses an upside-down "A".
He says this is general notation used by many mathmations but I can't find them anywhere online.
If someone could point me in the right direction...or even knows what I'm talking about?

The three dots means "therefore" (atleast my teacher uses it that way). The upside-down A is called a universal quantifier and means "for all", like "for all x element of P, R is true" (where P is a set and R is a statement).
