Calculator Tutorial - Intro to the TI-30XIIS

In this video, I go through the basic functions of the Texas Instruments TI-30XIIS scientific calculator. This scientific calculator, which features an equation operating system, has been the standard for Algebra courses for almost two decades. I go through the following calculator functions: negative signs, editing expressions, memory, number and angle modes, exponents, radicals, scientific notation, basic trigonometry, and pi.

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

[@TutorTerrific]

If you are going into undergrad physics, I would invest in a TI-83 or 84, any variant of those.

[@MG-ws2bp]

You are awesome. I didn't know how to do the inverse trig functions and couldn't find the answer anywhere till I saw you video. Thanks alot.

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.

[@TutorTerrific]

Well said. I like you username, BTW.

[@skipperry63]

[@c.f.beeble]

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.

[@itsmissy_]

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.

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?

[@TutorTerrific]

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.

Can you add large linear dimensions (20'-7-7/8) type numbers to another (2'-5-5/8)

[@TutorTerrific]

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.

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.

your video is confusing trying to review is there a way you can show to do fractions and do problems to show how it can be done please.

[@TutorTerrific]

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”
