    The textbook was in great condition and shipping was faster than expected. The value was amazing and I have no complaints. The text is authentic and official and the quality and appearance match those of others found in libraries and universities. The book came very protected and was wrapped in three different layers of protection and a carton box. I highly recommend this seller!

    Equation Solver

    I bought the Casio FX-991 ES. Fantastic for using Newton's law of approximation to solve equations like sinδ = a + bcos(δ + β) (a, b, β constants). Just substitute the ANS key for δ in the equation and keep hitting the "=" button till the answer doesn't change (converges).

  • Best Simple Display Calculator I've Used

    Best non graphing calculator for engineering courses I've used. Best part is being able to plug in human readable fractions.

  • Precise with great features

    I'm a student and this calculator helps me a lot to accomplish the math exercises required by class. Many functions are included, more than I will need actually but I loved the design, the big screen, the price and the ease of use.

  • Great for Digital Systems Design

    I recommend this model for CS studies and Electrical Engineering. It's real easy to calculate in non decimal base: base 2 8 and 16 and to convert it back to decimal. I think there are calculator models with a more robust screen. I guess that's why it's relatively cheap
