Welcome to Stacker, where we stack things up - but only in the right order! 😉
This powerful, yet humble, Reverse Polish Notation (RPN) calculator is here to make your life easier.
We know, it's not every day you encounter a calculator that loves postfix expressions as much as we do. 🤓

With Stacker, you'll experience the joy of crunching numbers without the hassle of parentheses. 🥴
Our calculator is so dedicated to the cause that it even lets you define your own functions - isn't that fantastic? 🚀

So, go ahead and give Stacker a spin! Just remember, if you ever feel lost, type "help" and we'll be there for you.
Happy stacking! 🎉
