Digital camera Review: Casio FX-115MS Plus Scientific Calculator
Summary: 5 Stars
This is a great product for the money. Fast and easy shipment. Would buy again from this sellerDigital camera Review: Casio FX-115MS, a very good calculator
Summary: 5 Stars
I have been a faithful user of the HP 48G since 1995. However I needed a calculator that is permitted on the EIT exam. Since I am comfortable with Reverse Polish Notation entry format, my first inclination was to look for a HP product that is approved for the exam. However after reading the reviews on-line and seeing the price of the HP33S, I decided to look for an alternative. The TI 30XIIs and the Casio fx-115MS were viable options at a better price. I bought both of the TI and the Casio for comparison.
Both calculators are about the same size, approximately 6"(T)X 3"(W)x1/2"(D). The feel of the buttons/keys on the TI was a bit dull when pressed. The Casio keys had slightly more engaged-feel when depressed. The engaged-button feel helps when I am keying numbers without looking at the screen to know whether the calculator took the string of digits and operators correctly. The color scheme employed for button labeling on the TI does not make the "2nd" functions stand out. This is made worse by the shadow cast by the tall buttons, which make the lettering for the "2nd" functions harder to read. The Casio uses fairly distinctive colors for lettering and function schemes. This makes it easier and faster to find the correct key.
I find that for engineering problems, Casio had more built in buttons. Thus I don't have to always use "shift" or "2nd" functions. I also liked the layout of the buttons on the Casio. I feel it is a bit easier to find the right keys, due to more logical key placement for certain functions. On the TI, I have to spend more time hunting down the button.
A few reviewers have noted that the Casio manual that comes with calculator to be mediocre. That is also my perception after reading through the manual. The TI came with a manual and a practice guide. The TI manual is more thorough and sequential in presenting the information. The TI practice guide presents some simple problems and show the keys that need to be pressed. This helps get the user to become familiar with the key layout and input sequence.
To overcome the mediocre Casio manual, I searched on the internet and found a tutorial on how to use the fx-115ms written by a math instructor for his or her students. The tutorial is fairly detailed and easy to follow.
Overall, both the TI 30XIIs and the Casio fx-115MS are very capable calculators. However I found the Casio to be more suitable for my needs. I would give this Casio product somewhere between 4.5 to 5 stars.

great calculator, integrates, derives, solves, only problem is figuring out how to do this. But best calculator for the Fundamentals of Engineering Test.Digital camera Review: Casio Rocks
Summary: 5 Stars
I definitely love my casio and its ability to do integrals. very good simple calculator that does my college physics and chemistry and calculus homework for me. Need i say more?Digital camera Review: Casio for FE Exam
Summary: 4 Stars
This calculator has so many functions to use that will be useful in the FE Exam, however, it becomes really difficult to figure out how to use these functions. One thing I found is that you cannot convert decimal to fraction while in engineering mode. Other than that, it is very useful.
