What math symbol is

The ∀ (for all) symbol is used in math to describe a variable in an expression. Typically, the symbol is used in an expression like this: ∀x ∈ R. In plain language, this expression means for all x in the set of real numbers. Then, this expression is usually followed by another statement that should be able to be proven true or false..

∀ (x, y ∈ A ∪ B; x ≠ y) x² − y² ≥ 0 For all (x, y :- A u B; x != y) x^2 - y^2 >= 0 The advantage of using plain Unicode is that you can copy & paste your text into any text file, e-mail message or HTML document and it will (usually) be displayed correctly without any special plugins.The double-struck capital letter I, I, is a symbol sometimes used instead of Z for the ring of integers.
