Why does 0! Equal 1?
That makes sense. Are there any other interesting mathematical conventions like that?
Actually, there are quite a few mathematical conventions that might seem strange or counterintuitive at first glance. One that comes to mind is dividing by zero, which is undefined in most systems of arithmetic. Another is the use of imaginary numbers, which involve the square root of negative numbers and were originally met with skepticism by mathematicians.
