2 reviews for HP 35s

  1. Per Liss

    Overall, a good calculator with what’s needed for professional use. There are anyway downsides:
    1. Entering an integrand for numerical integration is clumsy compared to HP-15C.
    2. Entering a program is clumsy compared genuine HP calculators such as HP-15C and HP-34C.
    3. Space for keyboard functions is wasted on rarely used unit conversions while often used functions are hidden in menues and reached with the arrow keys.
    When it comes to doing some more complex work I use my HP-15C or HP-11C instead.

    E’ peggiore come funzionalità di tastiera rispetto alla HP32S la quale però è orribile come estetica e comodità del tasto “Enter” rispetto alla HP 35
