 We can also find modular inverses through Euclidean Division.
 Given the prime modulus $m > a$ we have:
 $m = k \cdot a + r$, where k = $floor(\frac{m}{a})$	and $r = m \mod a$. Then: $0 = k \cdot a + r \mod m \iff r = -k \cdot a \mod m
-\iff r \cdot a^-1 = -k \mod m \iff a^-1 = -k \mod m \cdot r^-1 \mod m$.
+\iff r \cdot a^(-1) = -k \mod m \iff a^(-1) = -k \mod m \cdot r(^-1) \mod m$.
 
 Here is a short recursive implementation of the above formula:
