Mathmatical notation

If you do any computer science algorithm work, you soon run into mathematical notation. Below is a reference of common symbols used (will be expanded over time):

  • : such that
  • ⊂ subset
  • ∈ member
  • ∉ not member
  • ∪ Union
  • ∩ Intersection

  • ^ logical and
  • ∨ logical or
  • ⇒ implies
  • ⇔ is equivalent to
  • ∑ sum of
  • ∏ product of

ah yes, refreshed, I remember they were abundant in the programming languages course at the university.
