\Rightarrow
The \Rightarrow symbol is used in mathematical logic and proofs to denote implication or logical consequence. It signifies that if the statement on the left is true, then the statement on the right is also true.
If A is true, then B is true (logical implication).
A \Rightarrow B
If x is greater than 2, then x squared is greater than 4.
x > 2 \Rightarrow x^2 > 4
Chain of implications, meaning P implies Q and Q implies R.
