- A simple boolean expression validator, creating truth tables for boolean expressions
+# Boolean Algebra Expression Solver
+This application is a simple boolean algebra expression solver coded in C# using WPF. The purpose of this program was to help me learn WPF as well as utilise reverse polish notation and the shunting yard algorithm. This application takes a boolean expression as an input and outputs its corresponding truth table.
+
+## How To Use
+1. Insert the number of terms you wish to evaluate in the "Number Of Terms" textbox
+2. Insert your desired expression to be evaluated into the "Expression" textbox
+
+### Symbols Used
+The symbols used in this program include:
+* \* as __AND__
+* \+ as __OR__
+* ^ as __XOR__
+* ' as __NOT__
