I have added the following functions to a computer Im making with someone else. In the ALU, there are the following: Addition, OR, AND, NOT, XOR, NOR, NAND, XNOR. I see uses in the logic gates, but what are they used for in programs?

Splitting a spark to commence two different functions simultaneously? Honestly I myself don't know either.

Edit: To Do List; Learn how to make fusion reactors and how to make electronic devices.

I meant the uses in programs. Not creations. And btw I do know how to make electronic devices and reactors. But thanks for trying to help :)

It sounds like you misunderstood my "To-Do" list, which was describing what I need to improve on.

Oh, what do you mean by programs? In TPT or IRL?

(I wasn't trying to come across as a troll, I was just trying to share some of my background knowledge, just to clarify if anyone else thought otherwise.)

IRL or in the TPT computers.

"if this button and that button are down, then fly upwards" = AND gate
"if any of the two buttons are pressed, then turn off the light" = OR gate
"If one, but not two switches are down, then keep the light on" = XOR gate
"If the lights are not on, then turn on the IR lamps for cameras" = NOT gate.
"As long as two people don't pull these switches, hold the "SAFE" light on" = NAND gate.
Some IRL examples.

Thanks alot. That really helped :D

If you have some binary number,
and you need to invert its fourth bit you do number=number XOR 16
if you need to turn off that bit you do number=number AND 240
if you need to turn on that bit you do number=number OR 16

Yeah, bitwise operations too.

Thanks, but my computer can't control the amount of bit, so all logic operations are 6-bit.

Uses of logic functions?
