Finally a video that explains difference in features between 991EX and 991ES instead stating differences in their looks, solar cell or display. Keep up the good work sir.

[@MrsAbdelmoutaleb]

Thank you. I've recently bought this model, and I'm trying to teach myself how to use it. It is so much faster than the fx991 ES when doing integration.

[@avinavsharma7207]

Thank you so much, this was so helpful, i was wasting time on calculations I could've easily done on the device.

[@KulbirAhluwalia]

Amazing video! Well done !!!

[@OnlineToBrain]

Hello Sujoy sir, I have problems in this equation solve x(Cube)-2x(Square)-4x+8=0 But when i am going to solve this equation on my calculator it give me only X1 and X2 value why it don't give me the X3 value?????? Please help me and give the solution for this problems.

[@adamdanilowicz4252]

#Online To The Brain Do it without a calculator.

[@OnlineToBrain]

I know Aam and i can do it my self but that is not my problems my problems is why this eqn can't solve the calculator i mean why it dosen't give us the thiird variable ?????

[@OnlineToBrain]

I know Aam and i can do it my self but that is not my problems my problems is why this eqn can't solve the calculator i mean why it dosen't give us the thiird variable ?????

[@SkormGaming]

I know you might've figured it out now but when solved the equation only has 2 answers which is why the calculator is only giving you 2 answers. I'm guessing this is what Amam Danilowicz was hinting at. If your answers were x=2 and -2 then your calculator is correct as the root 2 is a repeated solution meaning that the one of the turning points on the graph lies on the x axis.

[@adamdanilowicz4252]

Ah yes, cubic graphs can sometimes hit at only 2 points.

[@marcogobbo6825]

Can you explain how to calculate mcm and mcd?

[@sujoy70]

MCM + MCD = MMMCCC

[@marcogobbo6825]

Sujoy Krishna Das i'm so sorry ahaha but what is mmmccc?

[@krishnashukla2729]

Can we take ex one in ese exam

[@NirajBind]

please tell what is the use of the button represented by ( - ) on the calculator.

[@sujoy70]

+Niraj Bind That's for putting minus (-) sign representing negative number. Subscribe to my KZbin channel so that when I upload a new video,you get notified. If you like any of my videos,I'd request you to please like & share it. Because sharing is caring :)

[@NirajBind]

+Sujoy Krishna Das Thanks for your answer. But i don't see the use of this button because all the operations that could be performed by this button can easily be performed using the regular minus button.

[@Crazytesseract]

+Niraj Bind exactly, but I think there is one function where only the (-) works... and I cannot remember what it is!

[@Crazytesseract]

+Niraj Bind Anyway there is one case where there is a difference. Suppose you calculate 5+2=7, and then want to continue with minus(Ans) * 3 = minus 21 (ie minus (7) *3= minus 21). After the first calculation you cannot use the [ - ] key to enter minus(Ans), because the calc will take it as Ans (minus) ... so you have to use the [( - )] key to enter minus(Ans).

[@NirajBind]

+Crazytesseract Thanks

[@anishasinha2801]

Is it a programmable calculator? Is it allowed in btech semester exams?

Casio calls it non-programmable. In my terms, it's Semi Programmable. In WBUT sem exams it's allowed. IDK about other boards. Check my answer on Quora- www.quora.com/Is-a-Casio-FX-991ES-programmable
