A Fifth Fundamental Operation of Arithmetic and the Beauty of Parallel Calculus

We all know the four basic operations of arithmetic: addition, subtraction, multiplication, and division. In school, we were all forced to trivially add and subtract numbers again and again, keep track of remainders, etc. until it was printed in our brains how these operations work. It is only much later we find out that there are really only two fundamental operations on the real numbers, namely addition and multiplication. Subtraction is just addition by a negative number and division is just multiplication by a fraction. <a href="https://www.cantorsparadise.com/a-fifth-fundamental-operation-of-arithmetic-and-the-beauty-of-parallel-calculus-93a2dfe28dda">Read More</a>
