Type 5->A to set a variable.
Have fun and remember to press Love-it!

Notes and Credits

This is an expression evaluator that I wrote using only 1 custom block. To use it on one of your projects, use the backpack to transfer the block to your project. NOTE: This project uses a hacked
[(sqrt) of (9)] block to be more compact.
Give suggestions for more operators and demos.
