This video was just what I was looking for. Straight to the point and no prolonged intro!

[@pdbass169]

Thank you so much for the helpful tutorial. You have a real talent for explaining and teaching. I can't wait to learn more from your videos.

[@watertriton]

I’m glad I didn’t know my Calculator did this when I was Learning. but I am happy that it can. Thanks for sharing this video.

[@englishman32257]

I have just recieved my Casio fx 991 Plus, thank for posting these videos, very help full.

[@esmashahin2167]

thank you! it's hard finding good videos for casio's, you're awesome

[@rosalyna.6620]

THANK YOU SOO MUCH!! I bought this calculator because of the modes but I didn't knew how to properly use it and it's potential.This video was very helpful. 😊

[@MrPsimmons3]

Thank you VERY much for this excellent tutorial!!! VERY well done!

[@hopefulmelancholy7514]

Thanks,man I can understand you so much better than my professor with her "Masters in math".🙄She may have a Masters in Math but her personality is really bossy etc. Plus she is one of those lazy professors that forces her Students to use MathXL. I wish everything wasn't so rushed in class.I keep you on my watch later playlist so hopefully I pass Intermediate Algebra this time.I'm in community college and the tutoring centers are mostly open during working hours. You're a great tutor. 👏📚📖😁🙌

[@vuruvwzlksz]

OH MY GOD THANK YOU MAN, i found out how to do this on my graphing calculator, but then my teacher said we cant use our graphing calc for the test, i was worried

[@kory1221B]

This video save me on my statics test today. Your instruction was awesome Thank a lot

[@kory1221B]

*saved

[@TheMetalButcher]

@@kory1221B It was nice of your statics professor to not do a 4x4 like mine did.... My casio did not save me on that one. xD

[@Wmann]

I’ve had this calculator for ages and I didn’t know this. Thank you so much, thank goodness I thought to myself “Hmm I don’t know much about this calculator, I’m gonna look it up”

[@michellegarcia7738]

Very helpful video! When I have multiple pens/pencils, I actually do the exact same thing as you!

[@enidgonzalez6314]

I loved loved your videos. Keep it coming! Thanks

[@blackpenredpen]

^_^ I am glad that you found it helpful!

[@sourcecreator2222]

I enjoyed the sound of your voice and you gave very good instruction. Very pleasant video to watch thank you my friend

[@hanna5514]

Thank you so much for this video! It is marvelously helpful.

[@moreoptions7942]

Thanks for the high quality video instruction.

[@ishowyouapple]

Love your style man. Awesome

[@EngineeringEducation]

Excellent video!! I highly recommend this calculator.

[@aljammal9891]

Amazing work .appreciate it I have final test next week

[@kieranpat]

Wow this is a throwback video, still helpful!!

[@Kay-dx8vm]

I wish I could give this video 10 likes, or I could subscribe it one more time. I picked this same calculator at Walmart for my engineering class ( I am a type of person who don't believe that I can only work things out with expensive calculators), but I gave up after a few times trying to find where to put system of equations, literally until now. Thanks a lot, man. Now I am back to a happy engineering student with a $15 calculator.

[@MyrtleBeachWebAngel]

Thank you so much. This was very helpful to me!

[@KalTheCleric]

Great job! I have the same calculator... and also the same pens!LOL!!! If you ever do a tutorial for the Casio Classpad II 400, let me know! Keep up the good work. :D

[@kyliesmommy84]

Thank you..truly. I appreciate this video

[@user-df3qe9cb3c]

Omg this was so helpful thank you!!

[@reandra38]

At Last! A simple but very effective video!

[@blackpenredpen]

Thank you! I also have made another video a few months ago, kzbin.info/www/bejne/bHfOhIBvZt9po6M hope you can get more out from this calculator! : )

[@reandra38]

do you have a video using fractions that contain ex: 7x/3-x=x/27-8/9

[@proudomani]

Thanks, excellent job.

[@jefejeffwell1113]

Huge help, brotha!

[@jasminecarter9594]

Thank you so much ! You are fantastic

[@amysmith8432]

THANK YOU! Can this calculator perform larger matrices than 3X4??

[@carmaster1693]

Hi blackpenredpen do you have playlist of video where i can found all of your videos about this casio calculator

[@smalltugz]

i found this calculator at my school last year i never knew it could do this kind of questions

[@hjjjhh5774]

Thank you!

[@CalehandJordan]

Thank you sir. Thank you.

[@McScubakis]

Thank you very much

[@johnredorn]

Thank you so much

[@rachelward2005]

🎉thank you!!!!

[@likeos2135]

I have used your videos getting ready for the Fundamentals of Engineering Exam... we are a huge market for your videos, add 'EIT' or 'FE exam' to the titles of your videos so others find you as well. Good videos, thanks!

[@blackpenredpen]

+likeos Thank you for the suggestion! I just added those keywords to my video. Best of luck on your FE exam

[@Killer97]

omg lol saaaaaaaame

[@jakieb689]

Thanks man. I wish I knew how to use the calc better on my last test.

[@blackpenredpen]

You're welcome

[@mrzombiesbo]

Should have learned this a long time ago lol, didn't realize it was this easy

[@RPS_Capital]

Thanks!

[@mbgames1007]

Thank you

[@nicolenc2140]

Thanks!!! :)

[@yarieskicasas5486]

Is it possible to find, using the calculator fx 115es plus, the gradient, divergence and curl of a vector? thank you

[@dirtybirdgaming8315]

Thank you soo mich

[@tombardier]

informative video, thank you. (but the music can be a bit maddening!)

[@tecengcivil]

Ola muito boa sua aula

[@TheMetalButcher]

So no way to do a 3x4 other than craymers rule huh? God I need a ti-89. Also, I like your dual pen setup.

[@coolcat1058]

How would you graph those equations on the calculator? Ex: x-y=3 X+y=5

[@harshitshirsat4127]

What could be the reason for MATH ERROR , in the above type of question but for some different equations

[@ianwong5470]

Hello, Just bought this calculator for school. Was wondering if it is capable of solving more than 3 equations with 3 unknowns, like 6 equations and 6 variables.

[@dchambers986]

Can you show a review of the TI 30x vs 36x?

[@sohailjanjua123]

Hi I like your video

[@mitchd1311]

How can you solve a system of equations with the unknowns being inside a trig function with this calculator without making substitutions? ex. -208.87cos(x)+y=0 and 248.9sin(x)+y=311.04

[@emlmm88]

It's great, but unless you have a _lot_ of equations, it might just be quicker to do the Gauss-Jordan elimination by hand.

[@jdriver75]

How do I store results from MODE 5:EQN? Say I solve a cubic equation and get 3 results for x. Sometime they're not displayed in simplified fashion, ie 1.414213562 instead of sqrt2. I'd like to use the S-D button there but it doesn't work. so the other solution is to copy an answer, go into MODE1:COMP and convert it there. But I can't figure out how to store the answer. Thanks.

[@agovics1]

Ty for all, is there a way that it solves a^x?????

[@SimplyPinoyNotSoRichRico]

WTF! whats the point of creating calculators if the teacher won't let me use it to solve these! "you gotta show work" what the heck, i just hate doing the work!!! Thanks mate good video

[@aoeronin9574]

Just do the initial work and get answer with calcand write down the answer, you should be fine

[@Killer97]

the point is these are for saving time not doing your work for you math courses require you to knnow these things but in other courses you can save time by using a calculator

[@aoeronin9574]

Shame that very few new people know their calculator

[@MyrtleBeachWebAngel]

It's hard to find great videos like these. I am glad I came across this channel.

[@blackpenredpen]

Thank you, I am glad to help!

[@dayrongarcia2604]

Is there a way to solve trigonometric definite integral using this calculator?? Thanks in advanced.

[@cydget644]

I'm back. Kate will accept vitamins.

[@polypoly4400]

Ans/0.1 how to solve

[@john-athancrow4169]

Its like 1.3 eh?

[@who6284]

nihau ma

[@zehraali5156]

Very bad writing ohhhh

[@livinguntohim1]

Thanks!!
