But they still haven't fixed the bug that you have to destroy wooden slaps with a pickaxe instead of a normal axe.
ITS NOT A *beep*ING BUG!
It's a glitch ffs. I assume it was because of their copy-pasting of the slab code that they forgot to change the properties when they made the wooden slab. Oh, and it IS fixed, a few snapshots ago.
Minecraft Wiki:
"As of 12w17a, wooden slabs have to be collected with an axe and they are affected by fire."

I don't understand.
> 1101 - 1110
First use a modified XOR gate to figure out all 4 combinations of both sign bits.
> +101 - +110
To figure out which number is larger than which, use this:
> The highest possible number with a signed 4 bit word is 1111, or +111.
> Lookahead the size starting from the end of the word, as +001 is always higher than +110
> Should there be the case where checking +111 and +011 happens and the first bit checked is 1, then move on to the next bit.
If the numbers conform (i.e the minuend is bigger than the subtrahend), then continue on as normal subtraction, +101 - +110 = +010
If the numbers don't, then switch up the numbers with mask circuitry and then invert the sign bit of the output.
EDIT: Uhh what's two's complement subtraction?
EDIT 2: I'm such an idiot with binary XD
Never heard of that inverting thing you're talking about. I really don't have much knowledge about binary algorithms, so this might be very inefficient.

16 bits give you a total of 65565 numbers, 2048 - 4096 = -2048.
Since it cant get any lower than zero, it resets and becomes 65565 - 2048 as the answer.
You solve this by making the numbers signed (using the first bit to denote if its positive or negative.) and solve it with a bit of extra wiring.

In a RS-NOR, you can interchange them with either input.

Output 1 = R NOR(1) Output 2
Output 2 = S NOR(2) Output 1
Assuming Output 1 is already on, the signal will go to NOR(2) therefore making output 2 off.
Say we put a signal on R, since there is no signal from either R or Output 2, it would be inverted and make Output 1 on in the first place.
Once we apply the signal, 1 will be off and then since 1 off, there will be no more on inputs on NOR(2), which makes 2 on.
EDIT: Nevermind, this .gif explains it better than me ^^
A DFF is much much different. Its basically 1 bit memory by itself. The output will never change state unless there a signal on the write input.
EDIT 2: Wow, I don't remember how long ago I have tried to make a calculator, I got bored and went on to pursue creative redstone. I have learned alot, more than enough to make a calculator, but you have got my will back to make one. Thank you.

I approve of this statement.
A computer is complex, but the operations you can make it do can be just as complex.
The approach to fixing programming problems can be applied to redstone problems.

You didnt build one in real life but you KNOW how to build one in real life.
Oh, and a subtractor is an indirect adder.
Instead of 1 - 1, its 1 + -1

You can try making a diode, but diode logic is more or less incomplete.

So, if a half adder is a HALF adder, you put another HALF to make it FULL.(lol)

I don't find it worth it. ^^
Why would I need that?
I mostly don't buy new things anymore.
1. Someone writes a greasemonkey script to remove ads.

There's usually a person who makes a client that can be used to play without a beta key/access. Just look at StarCraft II when it was beta, me and my brother EASILY found a client that indirectly launched the game and we could play.
