- This video will give you a complete overview of all of the functions that the Texas Instruments TI-30XA scientific calculator has to offer: from statistics to exponents through scientific notation, trigonometry and more.
Studying for a college final right now... You really helped me out here. I'm attached to my TI-83 but can't use it on the test. I didn't realize this little thing could do so much. Thank you!
Same here
Shelby Goodman same except I'm not in college
Dude, this is the only calculator I have, I rarely use and resent when I have to for an exam, but after watching your video my calculator workflow efficiency just went up 50%
i bought mine more than 10 years ago. probably 15 years ago. i just found it in the closet and then looked up this video.
One of the best scientific calculators for its price point!
I have used this calculator for the last 10 years and it really shines in its statistics and fraction-decimal conversion ability. Has enough functions to work but not so many that it is overly complicated.
Thanks ! Nice of you to show the freq and the sigma minus buttons for stats calculations. You can't know too much about your own calculator.
Neato. I'm in grade six middle school and don't understand a few things here, but pretty educational and interesting!
There should be a disclaimer to be proficient in these calculators BEFORE starting class. I have a few hours left to finish and here I am. Watching tutorials because everything I’m doing is butt ass wrong...Thanks for this vid!
Thank you very much for this video! Extremely concise and straightforward.
I love this little calculator.
thank you. you save me with the scientific notation!!!!
I didn't know how much this calculator could do until getting into statics, the only thing this calculator seems to be missing (at least to me) is matrices and graphing, but it's not a graphing calculator. I'm quite happy with it, and I can't even remember how long it's been since we bought it, and the batteries still haven't run out either.

THANK YOU DUDE YOU SAVED MY LIFE
I just found one of these in an old drawer at my parents house. Needless to say it's mine now 😮
Thanks for letting me know about it.
wow you just made my day. thanks so much!
Thank you so much!
Thank you!
You completely skipped over combinations and permutations :(
No clue what those are
Thank you v much. V informative.
should the DEG function always be on? I just need it for basic stuff.
I think the DEG/RAD/GRAD stuff should only matter if you're using the trig functions (like SIN, COS, TAN, etc.). Having it in "DEG" (degree) mode should be completely fine for just doing basic math.
so basically, yeah. it shouldn't matter for basic math. :)
@@shavono8402 what about factoring how to do it thru this calculator is it a graphing onr
How can I set this calculator up for the (') between a long numbers, for example 1'000'000'000. Now if I hit this long number, it doesn't show, which hard to read a long number without the (') separation. Thank you
Hi, Thuy. Unfortunately, I'm almost certain that there is no way to "set" the TI-30XA to display any type of "digit group separator".
Some regions of the world use commas (above or on the line), periods and even spaces to indicate digit group. Take a quick peek at these links to get a sense of what I mean. mathforum.org/library/drmath/view/63335.html
english.stackexchange.com/questions/110691/english-word-for-the-comma-between-three-digits
docs.oracle.com/cd/E19455-01/806-0169/overview-9/index.html
In my region, I'm accustomed to seeing numbers in this sort of format: 123,456.7890 (One hundred twenty-three thousand four hundred fifty-six point seven eight nine zero).
Unlike an operating system such as Microsoft Windows, which can be set to a region, my feeling is that the Texas Instrument TI-30XA is meant to be tamper resistance, making it a good calculator for use in organizations that do a lot of testing, such as schools and testing centers.
One thing that helped me see numbers with lots of digits was to remember that the screen holds exactly ten digits before it goes into scientific notation display. Nine billion, nine hundred ninety-nine million, nine hundred ninety-nine thousand, nine hundred and ninety-nine (9,999,999,999) can be displayed without scientific notation on this little calculator.
If this is your school's mandatory calculator for math and science courses you may find that the emphasis will be put on "significant digits" and "significant figures" so you will throw a lot of digits alway in the end.
I have 2 of these (one is a backup) and they got me through college algebra and trigonometry, calculus I and II. I'm brushing up with more of this little calculator's features in preparation for physics I and engineering statistics.
Hope you go far with yours and good luck.
There is no way on this calculator. Unfortunately, the decimal point is very difficult to see as well.
However, if you want, you can use ENG mode, which gives you scientific notation but only uses powers of 3. For example, typing 12334598 [=] while in ENG mode, it will give you 1.2334598 E 6. If you remember your metric prefixes, you can imagine that we're thinking about bytes, so this is hinting that it's like 1.23 megabytes. E3 would be kilobytes, E9 would be gigabytes, etc. It's not great but it's something.
Thank you!! :)
Thanks from me as well.
great video.. thx
How do I use the e^x button
For example the problem 1000e^(.16)(15)
Using the e^x key I’ve tried using the 2nd then hitting e^x but it says error
thank you
I prepared for college algebra (I am 52 and did not have in my prior 2 assoc degree course) I began with remedial math and then transfer math. I am still struggling
Tonya McCullough I understand your plight I'm 44 returning to school and I have to look up everything. Struggling is an understatement.
@@brexferral I hope you made it!
Thanks man, very helpfull
How do I set the calculator to show me whole numbers?? For example, if i add 1000 + 1000 it'll show me 2.03 instead of the obvious answer of 2000. :(
your calculator is on crack
This means that you're in SCI, ENG, or FIX modes. To get back to regular floating-point mode, press [2nd] [FLO] which is on the 4 key. If FIX is on, press [2nd] [FIX] and then the decimal key [.] to turn FIX mode off.
thank you so much
Is the ti30x a RPN calcuator?
Sucks that it doesn't have an answer button and doesn't show the current expression. Otherwise not bad.
u are a god!!
Thanks :)
I am struggling to use the "x!" function on this calculator. It's above the 3 button. Did I miss it in this video?
never mind #math
How are DeG and Grad mode different?
Degrees mode is the usual mode that people use, where there are 360° in a circle. Grad stands for "gradians" and it's a rarely-used system where there are 400 grads in a circle. Gradians are pretty much only used in some specialized fields in continental Europe, such as surveying in France. It's a holdover from the French Revolution, when it was thought that it made more sense for there to be 100 gradians in a right-angle, rather than 90°. Note that all this only affects trigonometric calculations (sin, cos, tan) and if you're doing some rectangular-to-polar conversions.
Most likely, you'll only use degrees (DEG), and in a math class, you might use radians (RAD).
I want give the binary and octal numbers with this calculator you can show me how to do it
The TI-30XA does not support octal, binary, or hexadecimal. Only decimal.
what about pe rt?
thx :3
I need help
How do I clear the memory?
Enter 0 into each memory address: press [0] [STO] 1 to clear out M1, [0] [STO] 2 to clear out M2, and [0] [STO] 3 to clear out M3.
Thank you. This is a horrible and non-intuitive piece of what can almost be described as engineering... But now I can at least use it with greater ease.
The reason why it's so confusing to use is that it's a continuation of the original TI-30, which came out in the early days of calculators and was largely responsible for the demise of the slide rule in the 1970s. Back then, calculators weren't very capable, so the idea of just typing something into a calculator as it appears on a sheet of paper was not really possible. It's at least somewhat more intuitive than the reverse-Polish notation used by early HP calculators, which functioned based on the concept of a computer's stack memory: you literally pushed various numbers into the stack memory and then pressed the operation to get it all going.
@@radishpineapple74 lmao. Good old postfix notation with a stack.
I have to use this piece of garbage for my Physics class. I hate it so much. Why is everything backwards???
You can’t even see the whole calculator
How can i do x-¹?
To do 5-¹ for example, you just press [5] and then [1/x] which gives you 0.2.
So I was using this calculator to test, I left the class and broke it, threw it in the dumpster. Failed miserably
RECOMMEND DO NOT BUY THIS STUPID ASS PEICE OF SHIT.
My Physics professor is forcing us to use this for his class. Literally the worst calculator I’ve ever used.
