## No Equal RPN Calculator Description
This scientific calculator uses Reverse Polish Notation (RPN), similar to most HP calculators produced since 1972.  RPN is more efficient for complex calculations.

Unlike many RPN calculators, the No Equal calculator always shows the stack.  This allows you to see both numbers before performing an operation, and it makes it easier to keep track of where you are in a complex calculation.

The No Equal calculator has 10 memory registers.

It also has a special function for solving quadratic equations (see the built-in help for details).

This is the initial release of the No Equal calculator.  Additional features will be coming soon.
