Enhancements...

Please see below:

1) The ability to clear all equations and start fresh with 1 click.
2) Add a settings to control the decimal places for the answer.
3) Add the ability to solve for any variables (Add Solver Capabilities)
4) Middle and High Schools student can use the ability to show the long hand steps by steps to the final answer. This would be a great tool young students to understand where they went wrong.
