    5.0 Stars no input errors noted .
  3. from www.amazon.com
    4.0 Stars in rpn mode, it is only possible to input two complex numbers on the stack, and the calculator does not keep track of the fact you've entered complex numbers.
  4. from www.amazon.com
    5.0 Stars i was a texas instruments user prior to owning this calculator, so the hp verision of inputing both numbers and then the operator is a little tough at first, but you get the hang of it easily.
  5. from www.amazon.com
    4.0 Stars but, and that is the main argument for or against buying it, it is not designed to be used in algebraic mode, which means you input the formula like it is written on paper.
