Well, once you've derived unary exp and ln you can get subtraction, which then gets you unary negation and you have addition.

Well, once you've derived unary exp and ln you can get subtraction, which then gets you unary negation and you have addition.
And then by using the fact that the exponential turns addition into multiplication, you get multiplication (and subtraction gives division).
