I know you need to use binary, but how do I do binary in LBP2, and after Icreate the binary numbers, how do I show it on screen? I found a website showing some of the logic used to make one.

I just saw that no one answered this, likely because the amount of space it would take to fully explain. The basic idea is, (at least how I would do it) to use analog signals that you display through whats essentially a signal probe to do your math. They have in built multiplying and adding feature, subtracting is the same as adding a negative, dividing is the sane as multiplying by the reciprocal. In the beta I had working trigonometry functions that you could apply to signals that I made by Taylor series expansions of the trig functions. I'm not sure how lbp3 handles >100% signals though, so that could affect the way you set it up if you need any decimal adjustment or anything. This is just a broad overview to give you some ideas.

Well, the cornerstone of binary arithmetic is the XOR gate which sums 2 bits. Start by looking up adders.

You'd use something like a seven-segment display. The decoder for one is pretty easy to make, it's just 10 (for BCD) or 16 (for full hexadecimal) AND gates, 7 OR gates and 4 NOT gates.
