And mathematicians divide by multiplying!
In formal definitions of arithmetics, division can be defined via multiplication: as a simplified example with real numbers, because a ÷ 2 is the same as a × 0.5, this means that if your axioms support multiplication you'll get division out of them for free (and this'll work for integers too, the definition is just a bit more involved.)
Mathematicians also subtract by adding, with the same logic as with division.

this is true... except when it isn't.
In mathematics, rings are algebraic structures that generalize fields: multiplication need not be commutative and multiplicative inverses need not exist
Computers multiply by adding, subtract by adding, i'm not sure how division goes but i'm sure that's addition too.
Looked into it. It literally is.
But....how?
Once you go down to logic gates. A XOR gate for example makes 1+1 = 0
