Hi there,

I was wondering what are peoples' preference for the 'type of input' when using a calculator?

The choices are:

1. Standard/Classic Algebraic

Like the Windows calculator and calculators from the 80's. For example, to enter:

sin(5) =

you press

5 [sin] [=]

2. Modern Algebraic

Like all modern algebraic calculators. To enter:

sin(5) =

you press:

[sin] 5 [=]

3. RPN
