That is a good guess and a useful concept. However, FYI, xor often means “an odd number of inputs are true”.

I actually don’t get “an odd number of inputs are true”.

@Elliot

Define or(x,y,z) using only operators that take 2 or fewer inputs.

I found or(x,y,z) = or(or(x,y),or(z,z)). Truth table:

I read ahead found this related to the assignment:

@Elliot

@Eternity

or(x,y,z) = or(or(x,y),or(y,z))

That’s correct but can you find a simpler or shorter answer?

I read ahead on accident and see that maybe or(or(x,y),z) is shorter? Since or(z,z) is identity then why not just use z by itself?

This is what i read accidentally ahead:

@Eternity

or(or(x,y),or(y,z)) = or(or(x,y), z)

ET said it was correct
