For real numbers, the multiplicative inverse for a number x is
x^(-1). This is another way of saying division.
Informal Proof:
x*x^(-1) = x^(1-1) = x^0 = 1.
In order for a process A to an inverse for some process B, when applied to B is must produce an Indentity.
If A is a sqaure matrix, and the inverse of B, then
A = B^(-1)
In this case AB = B^(-1)B = I, where I is the identity matrix.
In the case that A is a one by one matrix, it contains only 1 number, and so the particular process of matrix multiplication above reduces to division, and the Identity matrix reduces to the number 1.

Division, unless you want to multiply by an inverse, in which case you multiply by one over the number.
