HP Prime - Creating "Hello world" and transferring programs

Great tutorial! - Thank you :-)

Awesome, thank you so much!

Very helpful! Thank you very much!!

Thank you! Is it possible to store a number with an unit into a variable, as in the HP 50g?

Hi! Do you know how I can have the Prime output a matrice (non-string but arithmetic result) on the screen in its normal form? After switching to the Prime from my old TI-89 I'm trying to write programs in this new Calculator and I started with a program which uses Cramers matrices method to apply the Kirhoff's laws on electric circuit exercises and since I want to use this program in the school in the exam tests I want it to show me the solving procedure step by step so I can write it on paper. However, I couldn't unfortunately manage to have it output ec. "J1= [3x3 matrice] / [3x3 matrice]" except of the command PRINT which printed the matrix on a screen named "Terminal" but only in a one-dimensional way, so it literally printed in one line "[[1,2,3],[4,5,6][7,8,9]]" (no string) which is not what I want! isn't it possible to print results like on a chalkboard on this calculator? it was even possible on my ultra-old TI-89! Hope you can help coz it's very hard to find understandable info either online or in the Prime's manual!

Which programming language is this

all I get is syntax error

Hello examples are most useless. At least you could have written a program that computes all prime numbers for a given range, or anything else that would take input from a user, use a loop and if statement. You could also have these primes plotted on a graph and draw best fit curve. You have very powerful calculator and you demonstrate it’s abilities with hello world.

Terrible explainer. I'll go to a different video to find out how to ENTER a program.
