I have skimmed the first few posts in Eternity’s thread on the logic topic but mainly for any links/resources. I’ll mention if I remember anything from there if it comes up.

I started with this post [here:](https://discuss.criticalfallibilism.com/t/eternity-async-tutoring/1932/199)

1. Truth tables:

1. Evaluate expressions:

if:  
x = 1  
y = 1

1. xnor(and(x, y), x) = 1
2. nand(x, not(y)) = 1
3. xor(not(x), y) = 1
4. or(not(x), y) = 1
5. not(and(x, y)) = 0
6. XOR(NAND(NOT(x), y), y) = 0
7. NOT(XNOR(x, y)) = 0
8. AND(OR(NOT(x), y), y) = 1

if  
x = 1  
y = 0

1. xnor(and(x, y), x) = 0
2. nand(x, not(y)) = 0
3. xor(not(x), y) = 0
4. or(not(x), y) = 0
5. not(and(x, y)) = 1
6. XOR(NAND(NOT(x), y), y) = 1
7. NOT(XNOR(x, y)) = 1
8. AND(OR(NOT(x), y), y) = 0
