Casio fx-115ES Basics

Students really like this calculator, so I thought I would show you a few of its highlights.

[@hollywilson66]

YOU HAVE LITERALLY SAVED ME. I have been trying to get my calculator to stop my divisions going into scientific notation and just COULD NOT remember how to do it. Going back to college to do maths after 15 years. Thank you!!

[@Rico-ns5dt]

Life saver.. had this calculator since 2002. Forgot how to use it but need it for statistics to get my degree. Much appreciated 🙏🏻🧮

[@rickmorrow993]

Thanks. I found this old calculator I bought for my son in middle school. He's in his 3rd year of college now.

[@KaiE_37]

GOD BLESS YOU!! As a freshman this calculator was SOOOOOOOO difficult to learn from my previous non-graphing calculators. Thank you!!!!

[@antolin221]

SD button on Casio calculators stands for Standard to Decimal ( or Symbolic to Decimal).

[@xintrius7715]

Thank you so much for this tutorial, it helped out a ton.

[@drumtwo4seven]

Excellent calculator 👍 Great video too 👍 One more thing... The fraction 97/3 if you want it reduced (Shift) then (s-d) will reduce it for you 32 1/3

[@SM_x99]

THANK YOU SO MUCH God bless your soul🙌🙌🙌 And everyone good luck with your exams!

[@Abelmisi]

Kopsad: For finding out the roots of quadratic quations you can also try: Mode->5(EQN)->3 and plug in the coefficents. much faster than the formula and less chance of messing up

[@CharlesNDee]

Thanks for the video. Very helpful and I didn't have to wait too long to get the answer I was looking for.

[@MTViperGTS]

Thank you - just got one, definitely needed this tutorial

[@krishall3387]

The S on the S To D key stands for source. So it's "source to decimal"

[@iyamileth]

wow, I had no idea my cheap calculator had so much features. Very informative video!

[@DougQuick]

Thanks for this video! I was struggling just trying to figure out basic operations!

[@jumpythehat]

This one also has unit conversions and physical constants available, 40 each, printed on the inside of the protective cover. Very slick

[@ZacharyXAE]

I've been trying to figure out S to D for an hour, thank you.

[@gkirk54]

This was very helpful thank you!

[@s13rr4buf3]

Very helpful, thank you!

[@fashiondiva8276]

thank you so much !!!!!! this helped me big time

[@jessieeraee]

I love this calculator so much.

[@karenbonnetti-ramirez6264]

Very good tutorial! Thank you so much :)

[@daniels2183]

So helpful! Thanks

[@sarahlantsman5026]

This helped me so so so much! I watched 4 videos of weird old men with thick ascents that didn't help at all. Thank you so much!

[@subhageorge4360]

same

[@BlurryFaces]

LOL Me too!

[@somaro1996]

you are a life saver

[@828lexgirlgs]

Thanks this helped me a lot

[@scottheonly]

When I integrate and use "X" as the variable inside of my function, I come out with a syntax error. I noticed that the "dx" has a lower case x and I am entering in a capital. What can I do to fix this error? Thanks!

[@jlyssia83]

Thanks dude! Just saved my midterm grade loo

[@Gargola11NoTa]

awesome ... this video help me a lot, i buy it today :))))

[@chavitavb]

THANK YOU SO MUCH!

[@AG-sy4wt]

very nice for fighting vectors and polynomials in calc3/physics. I use it along with my ti84plus mostly b/c of radial simplication. very useful for linear analysis also, but the ti84 stomps on it for most stuff, ya this calculator flies low under the radar for semi new teachers where ti explicitly banned, don't expect seasoned professor to not check your gear though. I think there is a new version of this calc also thats the same price, then again this is an ancient video

[@xxCCBBxx]

press mode then 5 (EQN) to have a two variable system solver, three variable solver, quadratic, and cubic solvers

[@lottiebell5]

thanks for this i just got one and couldnt figure it out

[@Jeo1754]

Thx for the help

[@patrickmccormack4318]

Good calculator, good investment. Durable, reliable, long lasting, inexpensive, but not cheap, definitely not cheap. New Earth Army - 2nd Battalion "With pen on paper, we travel."

[@pnky2006]

OMG THANK YOU I WAS ABOUT TO GIVE UP ON THIS CALCULATOR PLESAE DO MORE ALGEBRA VIDEOS

[@leefo53]

When you press shift ans, what does the third option mean?

[@espyaceves]

F*** yea!!!! Thank you so much for your video and showing how to switch it from that scientific mode to decimal "normal" mode....I was dying here at home over that crap.....THANK YOU! THANK YOU! THANK YOU!

[@lovelylittleobsessions9951]

how do you get an infinity symbol on this calculator?

[@AznZanget]

Can someone help me? I have the fx-115 ES and on my display, the top part of the numbers are cut off.. Can someone help me?

[@mikerlasher]

Video was definitely helpful...Thanx, BUT, when I plug in the answer from an equation into another equation it is 50/50 that it comes up wrong. OR plug in 9 9/3 and push =. It comes up as 12. What am I doing wrong?

[@mography4563]

I LOVE YOU BRO.......

[@scottwolfe92]

I tried using fractions but it comes up with _|, what mode do you use?

[@chavitavb]

Do you know if this calculator is allowed in the act?

[@jennyarellano2311]

can you do standard deviation ? let me know the steps to check my answer

[@la-toshawilson5388]

Thanks for info. Can you tell me how to switch it to graph please? I am having the most difficult time with this problem.

[@leefo53]

A fx-115 ES plus casio calculator doesn't have graphing. I've tried.

[@chavitavb]

Can someone help me??? If I put something like 2.2 x 2.2 on this it gives me 121/25 as answer why :(?

[@kewalpatil4491]

Thanks a lot frnd

[@goofy103]

Can you upload a video showing how it works with a derivation?

[@koruptwon]

More more more!! :-D

[@kabralarmah7962]

For some reason when I multiply something be pi, it doesn't give me an answer. For example: 2pi and it gives me: 2pi. And when I try 2 x pi it gives me 2 pi

[@GreenTornado]

Kabral Armah It's giving you the answer in something called exact form because there is no accurate way to write 2pi in decimal format (pi never ends). However, if you want the decimal approximation, press the S-D button.

[@DynamicSoftball]

Or you could just use the quadratic function already programed into the calculator... thx for the tips!

[@zopilote_4000]

this calculator is so cool its basically cheating

[@proman3578]

Symbolic to Decimal?

[@mrlegendaryxp6255]

I have one and didn't know a thing about it

[@chengduFTW]

Is it possible to get an answer from previous calculations that I've done? I know to press Ans to get the answer I just got, but how do I get an answer a few lines back?

[@johnparks6936]

+KevinSui I know you posted this a while back, but did you figure anything out? I'm struggling with the same problem.

[@chengduFTW]

John Parks no clue, now when i do homework, i just make sure to assign all my answers to A-F just in case i need it later.

[@johnparks6936]

You assign them A-F on the calculator? How?

[@chengduFTW]

John Parks SHIFT -> RCL, then the respective buttons that correspond to the letter you want

[@johnparks6936]

Thanks!

[@StewartBroadcasting]

Where is the fact button?

[@bmoszk]

same

[@kathyw.854]

Does anyone know anywhere you can just read this sort of information? There are a billion of these videos and it's kinda frustrating having to watch every step. I know there are a lot of people who like videos, but even if someone who had a video also had a website you could read quickly and get out, that would be awesome!

[@XSevenSonata]

Casio's website has manuals. Just read or download a .pdf. You can look at the table of contents and skip to whatever page you want.

[@Abelmisi]

Press the button above DEL

[@sk8kels]

press the s-d button right above delete/

[@816fishingwitholiver5]

The calculator looks like my grandmas remote for her tv🤣no offense

[@mRUSSIA]

@bmw2go11 It is not powerful enough? Back in the 70's and 80's engineers were using calculators that were a lot less capable than this one. For instance, the HP-35 and the TI-30. They only had basic scientific functions with only one memory and no root solving capability or imaginary numbers, simultaneous equations etc. and they worked just fine. They just didn't have calculators back then that did everything for them. They had to use their brains.

[@scottwolfe92]

nvm I got it

[@chavitavb]

My friends has his test this Saturday so if anyone knows please tell me as we'll :)
