Calculation modes 
 
The HP 35s allows calculations to be made in “RPN” mode, in “algebraic” mode, or in “Equation” mode. Algebraic and 
Equation modes and programs are described in other training aids.  
 
RPN mode is the traditional way most HP calculators work. To add 1 and 2, keys are pressed in the order 
!#$. This mode is very suitable for calculations where the user is working towards a...

Arithmetic calculations with two numbers 
 
Now that the lengths of the two sides have been squared, it is necessary to add the two squares.

To add the two numbers, it is enough to press the add key.

In RPN mode addition takes the number from the X register, uses it, and puts the result in the X register, so the result is 
seen on the lower line. This is like a...
