 Big complex number calculation library for Go (with [math/big](https://pkg.go.dev/math/big)).
 
 Currently, the library supports:
 
 1. Gaussian integer, complex numbers whose real and imaginary parts are both integers:
 
-   ![gaussian_int](asset/image/gaussian_integer_formula.jpg)
+$$
+Z[i] = \{ a + bi \;|\; a, b \in \mathbb{Z} \}, \quad \text{where } i^2 = -1.
+$$
 
 2. Hurwitz quaternion, quaternions whose components are either all integers or all half-integers (halves of odd
    integers; a mixture of integers and half-integers is excluded):
 
-   ![hurwitz_int](asset/image/hurwitz_integer_formula.jpg)
+$$
+H = \{ a + bi + cj + dk \in \mathbb{H} \;|\; a, b, c, d \in \mathbb{Z} \; \text{or} \; b, c, d \in \mathbb{Z} + \frac{1}{2}  \}.
+$$
