Answers to Questions

How to write using Reverse Polish Notation?

The NPI notation displays operands before operators. One has to write operands first and then the order of operations.

a × (b + c) is written a b c + ×

dCode is not actually perfect and sometimes triggers an error with some complex formulas, please, excuse us.

Who uses Reverse Polish Notation?

The notation has the advantage that it no longer uses parentheses, reducing errors, and is sometimes faster than a normal calculation. RPN is also used in some programming languages like Forth, but also in HP calculators and in some scientific computations where the gain up and computation time can be interesting.
