That is LC3 assembly language, and you know what it does? It adds 4X4 matrices.

[SUGAAAAA]

I'd hate to think what it'd look like if they were 8X8 matrices....

You had to program on that evil simulator as well?

Good luck let me know if you need help.

SWEEEEET

And here I was deceived by Norton into thinking computer languages could be fun! I had picked up a free and pretty old copy of one of his books, (free education- can't beat that,) and it gave some basics on it. Turns out I'd probably think it was boring! What a shame.

What I don't get is why does everyone start the program at x3000

you don't have to you can start at x6000 or just leave it blank.
Older computers used to reserve the lower memory addresses.
If you leave it blank the program will run in the first available memory space.

Ah, so it's just tradition
