*Add two numbers Subtract two numbers …and from there all mathematics is possible…* And the same is true using only: NOT (a AND b) Which of course, is enough

*Add two numbers Subtract two numbers …and from there all mathematics is possible…* And the same is true using only: NOT (a AND b) Which of course, is enough for all mathematics, or to build any computer you’ve ever used. It may work more slowly, especially if it had achieved quantum supremacy, but still that one line of code essentially can do it all. I don’t mean to repeat the obvious here, but it’s always been fascinating to me and I’m not sure if it’s widely taught outside of first EE classes.*
