Does Xer mean all real numbers?
It means that "x is an element of every real number", so any numeric value for 'x' would be valid for the equation.
What does the E and R mean in math?
The symbol is ∈, not e. It is read out loud as "is an element of". So writing x∈R means "x is an element of R" (where R written in blackboard bold means the set of real numbers).10 Sept 2020
