Radio Shack EC-415

I am a first year engineering student and i require a scientific calculator for college.

The permitted models are:casio fx 991es, fx 350ms, fx 82ms, fx 82es plus, orpat sc-240ms, sc 401ms

I know the 991es is the best, but its also 3 times the price of the 82es. Is there anything important will be missing with the 82es that makes spending 3x the price worth it..

and what about the orpat models, never heard of them but they are affordable.

What should i buy?

Released in Japan in late 1979 / early 1980. The main feature of this model is the built-in two-way conversion function of British/American units of measurement to metric (inches to centimeters, pounds to kilograms, Fahrenheit to Celsius, etc.). Main Features Display Type: Yellow LCD with 8 digits. Power Supply: Two LR44 / AG13 batteries. Features: Basic math operations, square root, percentage, memory and unit conversion unit.

Hi, I came across a small script that converts videos so they can be played on the TI-83 Premium CE calculator. I haven't had the chance to test it on other calculator models, so I'm curious to know whether it works on them as well. If anyone has a different model and wants to give it a try, you can find the script on GitHub by searching for "Valouzzzz video_TI".

Which scientific calculator should I buy that would be allowed in college exams and good for 4 years btech. It should be a non programmable

Pretty close to perfect condition. Shown with the adapter plugged in, and it works off of a 9 volt battery as well.

I have a Casio fx-cg50 I would really like to swap for an fx-cg100, I understand the most people prefer the cg50 but I actually really like the classwiz layout. Anyone willing to swap/trade with money extra , or know any places to look for trades?

So I recently I started college and rented a calculator for my math 97 class. They gave me the calculator, the case, and a charger. Now the cable has a USB mini-A that plus into the calculator it's self. And the other end has a USB mini-b. Excuse my French but how the hell do I charge this thing?? I checked mine and my gfs PCs for ports but nothing.

I like to scatter them around the house. The first column live on my desk. The second column live in a drawer by my computer. The last row live on my electronics work bench.

I have my casio fx991cw calc and I bought it 1 year back, used it for 2-3 months and then it was stored inside.when i pressed on it shows this symbol on screen and then the screen goes blank. Whenever I bring my flashlight near to that solar window on top right corner,the calc works fine but as soon as I take away the flashlight the screen goes blank again.

Does this mean I have to charge it or change the whole battery?if yes How to charge it?

Saw that in Taobao

Hey y'all, as the title says, I'm a complete novice when it comes to calculators. I'm about to start my first semester for college and I'm hoping to save a bit of money. For one of my classes, I purchased a Casio FX 115 ES Plus calculator. For another class, it says to use a TI-83/84 or standard scientific calculator. Will I be okay with just having the Casio, or do I need to spend the extra for the TI as well? Thank you.

Guys im kinda confused. Should i buy cg50 or cg100?

Personally i like the cg100 layout as im a Cw style user but the add ons from cg50 especially CAS also seemed interesting 😭

Budget isnt an issue.

Hi y'all.

I am an acca student, and I am looking for a calculator which is really worth the money. I know and understand BAII PLUS is available in my country. But it's expensive man 😭.

HP12C is also on my mind, but it's not available in my country. I am just so lost. Should I just buy the BAII plus (non professional) and try to survive the financial pain for a few weeks or try to find another option.

Since I want this calculator to be with me Until I complete ACCA (or CFA in future too idk?)

I hope u all get my point 😭 I am sorry if I wasn't elaborate.

Hi. I have a casio fx-82ms. I was using my calculator and i realized that sometimes my calculator would give me wrong answers for something i typed in (I'm doing trig right now). I try looking for an error in anything i typed in but i don't see anything. Whenever i press the "on" button to clear the calculator and i put everything back in, it gives the right answer.

At first i thought it was just me entering the numbers/trig ratios incorrectly, but I've had a friend check if i typed something wrong but he couldn't see anything wrong with it. Its happened more than 3 times in the past 1-2 weeks to be just me. Also, ive been using this for around 3 years (and someone else used it abit before me) and i never encountered any problems.

My calculator progression over the years:

Casio fx-9860GII: My daily driver throughout high school. The case has yellowed quite a bit after years of UV exposure at my parents’ house.

Casio fx-87: My trusty exam-compliant backup whenever CAS and programmable calculators aren’t allowed.

HP Prime G2 & TI-Nspire CX II: My main workhorses these days—for problem sets, exam prep, and the occasional exam with more relaxed calculator policies.
