I appreciate that algebraic mode is available because if I am not sure that I am entering a calculation in RPN correctly, I can double-check myself in ALG mode.

Once you’ve done a bit in RPN you’ll soon realise you’ll feel more confident that your RPN answer will come out with the right answer because you’re less likely to get muddled up with brackets entering a calculation like you might on a non-RPN Calc.

Try (13+3)÷(4×2) for instance in both modes
