I'm already so done with this course.

My textbook:

p: "The weather is bad."

Exercise:

Represent "the weather is good" using logical symbols.

Me: How am I supposed to answer that? You didn't give me a letter for that. I guess I'll use q?

Expected answer: ~p

THIS IS LITERALLY THE CLASS ABOUT LOGIC DHDJFBDHDJDHDHDH

I tool a sql class, so if the trinary logic is True, False, and Null then I don't have to imagine it, I already learned it.

I suppose you could have "true", "false", and "unknown" too. That could be interesting. But it wouldn't look all that different - AND compares the values and returns the less certain of the two. OR compares values and returns the more certain of the two. Unknown inverted is still unknown. Not that hard.

Qbits have four states, I think? Now those are fun truth tables.

Can you construct a truth table for a trinary logic system half adder?

[-] SuperNovaStar 1 points 6 days ago

Probably? I don't feel like doing homework rn, though, and what would be the point?

Some programs might have reasons to add an additional truth value, (for example, most databases include "NULL") but trinary would be a terrible choice for hardware. The tolerances are just much more forgiving when you're detecting the presence/absence of a charge than trying to measure multiple distinct states.
