  • Summary: Excellent calculator for Computer Scientists
  • Comment: Not all scientific calculators are created equal: different capabilities are presented by different models depending on what disciplines they support. I needed a new scientific calculator, but wanted one that made quick computer science calculations easy.

    After shopping unsuccessfully for some time, I stumbled upon this model one day in a Staples. I was pleasantly surprised to see that it had three different logarithm keys: one for natural logs, one for log base ten, and a third which allows the base to be inserted as a variable. Since many computer science calculations require base two logarithms, I was overjoyed. Then I saw it had keys supporting the following bases: 2, 8, 16, and 10. My jaw dropped when I saw how inexpensive it was, so I quickly bought it.

    I have used this calculator quite a bit. I'm not rough on such things, but a couple years of use has not led to any problems. The display allows me to see both what I have typed in and the answer, so I can confirm the calculation is what I wanted. A small solar panel helps power the device. I like the reversible slide-off cover better than the flip-cover of my older Sharp calculator. This calculator is light weight and just over half an inch thick, so it slips easily inside a briefcase or pack.

  • Summary: Ultimate FE/EIT Calculator
  • Comment: If you're wondering which calculator to buy for the FE exam. Get this one (Casio-115ES). In comparison with all the other calculators out there, this one does the most for you. Make sure to buy the "ES" and not the other model. This calculator can do more functions (for example: Matrices) than the TI, HP, or other model Casio's that are approved test taking calculators.

    Just wanted to throw that out there.

  • Summary: Almost the perfect calculator!
  • Comment: I think this is really one of the best calculators in the world. Infact as an engineer I prefer this too Ti-89s etc. Its way better than Texas Instruments calculators that are so common. If you get really good with this, it will make you nearly twice as efficient than your counterparts.

    Im forgetting what other things casio could probably add as useful functions to the calculator. Also just be forewarned that some of the functions that use the newton's method to calculate stuff can be notoriously wrong. However this is not the calculators fault, rather its the intracrasies of doing it in a calculator instead. Any other calculator might give you the same troubles too.

    All in all this is one calculator that is most useful, yet legal enough to be allowed in LSATs/SATs etc. etc. and other engineering exams and courses.

    Get this and you won't regret it. Don't waste your time with other calculators.

  • Summary: Couldn't live without it!
  • Comment: I bought this calculator in 9th grade for Geometry and it wasn't really a huge help. It had cos, sin, tan, and all that stuff, but it wasn't anything special or anything. Geometry was mostly just memorizing the rules.
    However, 10th grade came along with Algebra 2 and this calculator helped immensely.
    I love the 2 line format and how it types out like how you would write in down on paper. It's really easy to go back and look for silly mistakes, like +/-.
    A great calculator that makes fractions in fractions so much easier.
