How to use a TI 30X IIS calculator

How to use some of the essential funcitons on your calculator. Please leave comments if you have any questions or you have questions about how to do other things on your calculator.

[@DonnaTN]

GOD BLESS YOU!!! You make this SO clear and easy to understand! PLEASE DO MORE WITH THE TI30XIIS calculator! Nobody EVER explained all of that to me before! The last time I took a math class was 35 years ago! (And we DIDN'T have calculators THIS confusing... if any!) In my Statistics class (BER345) I think the teacher assumes we understand HOW to use EVERYTHING on this calculator (mentioned above!) PLEASE DO MORE VIDEOS on EVERY SINGLE type of function you can do on this calculator! Thank you SOOOOOOOOOOOOOOOOOOOOO much!!! GOD BLESS YOU!

This was a great video. My 7th grader was advised to get this calculator for school. I know he is going to be overwhelmed by all of the buttons. Your video covered the types of calculations he will need it for. This is perfect.

[@robhenderson1832]

Miigwetch! Thank you so much. As an old 50 something I need all the tricks I can find to pass this Math 040. This helps immensely.

[@TheOlavarria49]

And I thank you for that!!! I just got this calculator and didn't know how to use some of its functions, now I do. thanx!

[@ladypinkbagsetc.9116]

Wow Amazing! I have been trying to find out how to use this for 3 days... You did it in 6 minutes! BRAVO!!! I did not know what these were. I am studying to pass my Math GED and was lost... I missed it by 2 points because I did not know how to use the calculator. Thank you so much. My test is on the 5th of November. I have passed all of the rest .

[@mariellemusm.8039]

I have like 2 days with this one and I also need my math hiset equivalent ged for 4 days

[@laurieclay6791]

Thank you you helped a lot and I found a graphing calculator and am now only a few lessons from finishing my algebra book thanks again.😊

[@shafferjoe1962]

Thank you... You hit what I was wanting to find out in one video... Great job...

[@kevinkennedy503]

To do e to the - 7 power find the e^x function (it's the secondary function for Ln) and then put in - 7 (make sure to use the ( - ) and not the subtraction button) OR find the e constant and then use the ^ function and then put -7 (again make sure to use the ( - ) and not the - subtraction button)

[@roschellerumley3566]

thank you. i've watched serial videos but i understood you. Please do more, i'm stating class in Aug and i have never used an scientific calculator so thank you again. Signed Frustrated

[@kevinkennedy503]

Sven: The calculator does not have a generic Log function. It has two fixed based log functions: Log, which is log base 10, and Ln, which is log base e. If you want to evaluate a log in a different base you need to use the change of basis formula: Log(base a) of b = Log(b)/Log(a) So in your example you would use Log(9)/Log(3) to get 2 I hope that helps.

Thanks for posting this video! It was very helpful to me.

[@programmingjo]

excelent tutorial!!! it really helped me to understand the basics of it! would you be kind to do a tutorial about how to do algebraic computations on this calculator? I know is not designed for that purpose but I know that you know a way to do it, so, please! I'll really appreciate it!

[@kevinkennedy503]

What do you mean exactly? If you're talking about simplifying expressions with variables then answer is no, it can't.

[@angelicamejia1163]

Omg thank you a was really bad and my teacher of mathematics is going to be bad of me thanks for saving me life

And pls do mor videos with the ti-30x11s

[@mightymike4706]

In other calculators there is a x to the power of y button (it looks like a x with a little y by the top right corner). What is it on the Texas Unstrument TI-30X IIS?

[@isaacpolanco9732]

good morning how can i plug in an slope formula, like : y=mx+b or 3=1/2(4)+b Thanks

hello i wonder how to turn mixed numbers into decimals on this calculator

[@kevinkennedy503]

On your calculator you should see a function that says "f< >d". I think it comes up in the video.

[@sven96haller]

How do I give in Log3 9= 2 to get the answer of this: 3^x = 9 If I press Log it takes Log10 9 (lg 9)

[@chelseapierrevil5922]

thank you

[@xanderfloats]

What about radicals? For example square root of 80 always gives me a decimal. Is there a way on this calculator to get that radicand in simplest form, while still being a radical?

[@kevinkennedy503]

Alexander Galdamez This calculator cannot simplify radicals in radical form. The TI 30XS can. This one cannot. I plan on putting out another video soon on how to simplify radicals.

[@jlpetty85]

I need to figure out how to put negative numbers under a radical sign. I have tried using the (-) negative button next to the 0, but it comes up as "domain error".

[@kevinkennedy503]

+Jenna Petty Whenever you take the square root of a negative number, you get a complex number as a result. The TI 30X IIS cannot do calculations with complex numbers. You're getting that "domain error" because you are typing the calculation correctly but, since the answer is a complex number, your calculator cannot give you a result. If you're attempting to find a square root of a negative number, remove the negative sign and bring it out of the radical as "i". Then find the square root of the positive number remaining. If you're doing this as part of using the quadratic formula then that means your equation has no real roots.

[@kota69420]

I was messing around with PRB button and I pressed something and it brought me to the alphabet I put a. does anyone know how I can do it again

[@TheLukrie]

Nice men... cool

[@pablotafur539]

How do you multiply fractions? Such as (27 and 2/3) times 1/2

[@kevinkennedy503]

This is covered in the video. You use the fraction button (the a b/c button). Type in in this example, 27 a b/c 2 a b/c 3 * 1 a b/c 2. You're going to get a mixed number when you do this. If you need to convert it to an improper fraction that's covered in the video as well.

[@marianasalazar8150]

how would i type in x for example cos(x)=12/13

[@kevinkennedy503]

Masumi: I am actually in the process of uploading a video on how to use your calculator for scientiffic notation.

[@ethanbonyad2526]

Excelent! 👍

[@scotness]

how about Polynomial and multiply radicals? you are doing the easy stuff but If you can do those two I would do my happy dance

[@kevinkennedy503]

You can't multiply polynomials or radicals with the TI30 XIIS. Most calculators won't do variable operations. Some calculators like the TI30 S or the TI83 will do radical operations if they are set to Mathprint mode. The TI 30 XIIS doesn't have a Mathprint mode (to the best of my knowledge). Sorry

[@krishuber1732]

Where can i find the abc button on my Ti-34II ?

[@madisonrudkin5430]

Thanks so much for this! SO helpful! I do a question, though. I am doing college chemistry right now and need to find the rate constant using a calculator. On most calculators people use a STAT button... does mine have that ability? I see a STATVAR button... I would so appreciate any help.

[@madisonrudkin5430]

+My Joyful Noise Never mind! I just found out how to do it. =)

[@WeekendScheme417]

Can you graph and create tables on this?

[@jrcgjhughes]

What do you do when you have a negative for example 11 with a - 4 power x 11 with a -4 power ? thanks

[@kevinkennedy503]

Type in: 11^-4 x 11^-4. You will end up with a decimal. You should be able to use the 2nd, fd function to convert it to a fraction (although in this case it may be too large to convert). Alternately: without the calculator your answer would be 11^-8 or 1/(11^8)

[@tango108]

How do you use it if it's natural l9g division ?

[@kellyhatz4977]

what about square roots? what keys do I use?

[@deejay6869]

Thanks for this video. I downloaded the Instructioj Manual (.pdf) for this calculator, but all I got was a teacher's instruction guide. It might as well have been reading a Jurisprudence legal document, for as much sense as it made to me. Just curious: Do you have that manual to look over? And is it just me, and it's ridiculous in its ex;planations? Or does it make perfect sense to you? I'm new to scientific calculators, so it may just be my inexperience. Have you, or could you, done/do a review of the different calculator buttons? Just a quick explanation of what the different buttons are designed to do. Else I fear I'll have to traipse into the teacher's guide some more. Ugh.

[@malikasee8404]

Thanks

[@hashtags6051]

thanks man!!!

[@Youngacefunsessions]

how about inverse trigs? it show domain error?

[@ScarletxVelvet]

When I calculate 6.9 x 10^-8 and divide it by 4, I get 0.000000017. However, I should be getting 0.00000001725 like in other calculators. How can I view more numbers?

[@kevinkennedy503]

+ScarletxVelvet : good question. One option you have is to switch to scientific notation mode. See my video here: kzbin.info/www/bejne/qXOYZmV4frl6d6c
