Hi Melissa, I'm 54 and back in uni for the first time in 20-something years. I've never used a scientific calculator in my life and your video is exactly what I needed. Coincidentally, I bought the same calculator (TI-30Xa) which is an extra bonus for me. Thank you, Thank You, THANK YOU!!!
The part about the parentheses is SUPER important, especially with a TI-39XS which has x10^ rather than E or EE, since it treats the x10^ as a separate and distinct multiplication. This is a problem! Especially when doing division, as it will NOT group the exponent as part of the number, and will try to divide the exponent itself. To work around this, make sure students include exponentiated numbers in parenthesis. 1.23E15 / 3.45E-10 Is NOT the same as 1.23 x 1015 / 3.45 x 10-10 But (1.23 x 1015 )/ (3.45 x 10-10) is.
For the last problem, it is better to alternate division and multiplication instead of multiplying all numerator's factors, then denominator's factors, and then dividing them up. Not only this requires less keypresses, reduces chances of making erors with parenthesis, but also reduces possibility of overflows/underflows and reduces error accumulation.

Creative teaching.thanks
Thank you! great job! fast right to the point
You're a life saver!
I have a TI-84 Plus CE, and the "2nd" functions are WAY different than that of a TI-30.
Thank you; easy to follow and understand.
OMG THANK YOU SO MUCH!
Thank you so much!!!
Thank you !!!!!
THANKS!!!!
Thanks so much
Very helpful video 😀

So helpful thanks...
Thank you so much for the amazing video ^^ ♡♡
This was useful
Your translation Tex is covering the calculator so you can't see what button you are using.
You are amazing, thank you.
Thanck u
My Calculator has all the buttons except DRG, LN and a few other Shift/2nd Features... Is this Normal to you?
How do I input the symbol ^ on a scientific calculator?
This was useful and
