Thank you for carefully showing us the keystrokes. Many calculator and software instructors show off their speed and it requires us to pause and go back over and over again to see what they did.

blackpenredpen It means "very good" in Portuguese. Great video! I love the way you speak!

[@TheBigBigSean]

Why is it when I press -3 to the 2nd power it comes up -9? It should be positive 9. Can you help me? Are my settings wrong? Thank you.

[@blackpenredpen]

Hi there, you need to use parenthesis if you meant (-3)^2 , which is 9 but if the question is written as -3^2, the correct answer is -9

[@TheBigBigSean]

Thank you!

My Calculator Is Not Like Yours, It's a casio fx-991es plus, It still has good functions though! I'm 10 years-old by the way, Plus I'm in 5th grade, I know equations from 6th grade, 7th, and even from college! Let's have a good equation time and compare our calculators and do some equatiins on a livestream and film your video, Okay?
