Online boolean calculators seem to be few and far between. So here is one I made.\n";

\n";
echo "- Use an apostrophy ( ' ) for 'not' (can handle double nots too)- X = (A' + B'' + C''')
\n";

\n";
echo "- Two variables together is an 'and' - X = (AB)
\n";
echo "- A plus ( + ) is an 'or' - X = (A'B) + (C)
\n";
echo "- Will simplify and'd brackets - X = (A'+B)(AC) + (CC)+ (AC) = (A'AC + ABC) + (CC) + (AC)
\n";
echo "- Will simplify redundant variables - X = (A'AC + ABC) + (CC)+ (AC) = (A'AC + ABC) + (C) + (AC)
\n";
echo "- Will cancel opposing variables - X = (A'AC + ABC) + (C)+ (AC) = (ABC) + (C) + (AC)
\n";
echo "- Will simplify redundant terms - X = (ABC) + (C) + (AC) = (C)
\n";
echo "- Currently the calculator only accepts 'A', 'B', 'C', and 'D' as variables
\n";
echo "- The calculator is rather fragile, nested brackets won't work - X = ((AB+C) + AC)(BC) won't work
\n";
echo "- It doesn't do demorgans at the moment. Sorry - X = (A'B+C)' + (BC)' won't work
