thank you so much for this tutorial. i have had this calculator for years ever since high school, now going onto undergrad physics, and ive wanted to learn what the other buttons do. thanks for showing the FLO, SCI, and ENG buttons! they really help
The Texas Instrument's TI 30x iis scientific calculator is a nice item to have in any emergency or just for everyday use. It has many features, including a scientific and engineering mode. As well as a square root feature and many other functions, this calculator is good to have for the price. They're durable and reliable. They'll last for many years.
Hello, great video. I need to know how to calculate scientific notation with 10 raised to a negative exponent. Thank you very much for the great tutorial.
Great video. I've been using my TI-30XIIS for years, and I love its intuitive key and function layout. But there is one very important caveat, concerning negative number entry: If you enter, say "1 + -5^2" it will give "-24" (not the correct "26"). The calculator recognizes the "5^2" but does not apply the negative sign until the end! BEWARE OF THIS, because the TI-30 does this with all exponential functions performed on negative numbers that are entered "live". To work around this, you need to enter "-5" FIRST, and press "=", and only THEN continue with "1 + ANS^2". Alternately, you could add parentheses: "1 + (-5)^2" also gives the correct answer. It's a minor issue, but it can really mess with your head, (and your answers!), in entering quadratic equations, if you aren't aware of it. Many calculators make you enter a number first, BEFORE pressing a "+/-" key, and then its negative status is immediately applied. This works better, I think, so I hope the good folks at TI are listening.
Isn't there a difference between -5^2 and (-5)^2 in the first place? -5^2 is when you do 5*5, then apply the negative sign in front to get -25. (-5)^2 is when you do -5*-5, which gives you 25.
Do you have video to show full statistics capabilities with this calculator? I am trying to find how to perform norm distribution (or z values). I see there is RP shift icon which I am assuming is to find area under Right (R) or Left (P). Not sure how to implement that. Thanks!
Tutor Terrific, what are the commas for and what do they do? Whenever I use them for something like "1,000,000 + 1,000" I get "SYNTAX Error." What are they for and what is the correct way to use them?
Do not use the commas when entering large numbers. Enter those numbers without the commas that you would use if you were writing them on paper. For example, enter 1 million as 1000000. The commas are used in the statistics features of the calculator, as far as I know.
Is there a way to root over a number from a previous calculation without having to clear the calculator and put in the number again? Anyways, thanks for this, very good tutorial.
My friend has one of these TI-30XIIS. I have a TI30XA. My x root of y is used with the y entered first. His X root is used with the x entered first. I have used TI calculators for 50 years, and this is my first complaint
These calculators don't solve algebra equations. 1. Add 5 to both sides of the equation. You will have 4x=28 2. Divide both sides by 4. You will have x=7 Done.
Per fraction to decimal, all you have to do is and put the fraction with the numerator and denominator separated by the division sign, and press enter. It will automatically convert it into a decimal. I do not believe this particular can do the opposite.
Wait, are those 20 feet and 7 and 7/8 inches and 2 feet and 5 and 5/8 inches? I don’t think this particular calculator can decipher multi dimensional measurements. You would have to convert to either to feet in decimal or inches in decimal for both numbers.
Yes you can, if you have a fraction, type in the numerator, then the division key, then the denominator, and press enter. For square roots, type the square root key and then type what is inside the square root, then press enter.
TI 81? Those are so old! No one uses those anymore and you would e hard pressed to find someone who could help you with it. Also, lots of classes don't allow graphing calculators because graphing needs to be done by hand.
@@TutorTerrific The manual is free online, and they're definitely better than anything in the ti-30 series. By "a lot of classes" I'm assuming you mean before Algebra 2, which I'm not talking about
To input fractions on this little calculator, you have to do it and old-fashioned way. There’s no special math type view, so fractions have to be input like this: (numerator/denimonator). So, for example, you need to write (2/5) to input “two fifths”. If either your numerator, denominator, or both have multiple numbers added or multiplied together, you need to put in each in a separate set of parentheses so as not confuse order of operations on the calculator. For example (3/(2x5)) would calculate “three divided by two and 5 multiplied together”
Ha ha! The percentage sign is written right after a number, which will essentially just divide the preceding number by 100. So, if you type in 3% and press enter, you should get .03
Isaac Vargas You would need to reset the calculator. To do that you would press the 2nd button and 0. Your screen would then say “RESET: N Y”, which you would select N by pressing the right arrow. Press ENTER and your memory will be cleared, you can just press the clear button to start using it again.
If you are asking me to help you simplify this, start by removing parentheses correctly (distribute the minus sign) and then combine like terms: 2x + 4y + x - 3y answer: 3x + y
Lol, you mean "syntax error"? You need to check in what you are typing, do not interchange the minus sign with the negative sign, for example. Do not type ")" if you have not already typed "("
Well, from a teacher standpoint, which I have, calculators cannot save you when you are I'm sure it's a procedure that you must know. While a calculator can complete some message for you, It cannot complete problems from start to finish on its own.
This calculator is the reason an entire generation is bad at math. They wouldn't let us solve problems in our heads they had to make the calculator do it.
This one, specifically? No, it's the parents' and teachers' reliance upon all the TI, Casio, and the other calculators, all the way from four function to graphing, that have done this. Since posting this, I've switched to classical model of education, and no calculators are allowed to be used all the way up to seventh grade, where they can be introduced for very specific things only.
@@TutorTerrific two years later lol I know it’s not your fault but I’ve already given up my masters degree because I couldn’t pass the praxis in the math. It was ridiculous what they wanted elementary teachers to learn. I made a video about it but then I deleted it I sent it to school board presidents, and county commissioners but I never got a response.
I'm sorry to hear this, but you are right that it is ridiculous, especially considering with the average elementary public school class in this country actually looks like on a day-to-day basis. If you ever decide to get back into it, I have spots available during the week in the evenings.
