该博客介绍如何在Python中实现有理数的加、减、乘、除四则运算，包括处理特殊值如0和无穷。讨论了转换为加法和乘法的逆运算，以及输出格式的注意事项，特别是负数需要括号包围。博主提醒注意0/0的处理，并提出了对代码的思考和改进，包括不同无穷情况的运算处理。

题目如下：

For two rational numbers, your task is to implement the basic arithmetics, that is, to calculate their sum, difference,
product and quotient.

输入描述:

Each input file contains one test case, which gives in one line the two rational numbers in the format "a1/b1 a2/b2". 

The numerators and the denominators are all in the range of long int. If there is a negative sign, it must appear only in 

front of the numerator. The denominators are guaranteed to be non-zero numbers.

输出描述:

For each test case, print in 4 lines the sum, difference, product and quotient of the two rational numbers, respectively. The format of each 

line is "number1 operator number2 = result". Notice that all the rational numbers must be in their simplest form "k a/b", where k is 

the integer part, and a/
