多元多项式运算 主要用C++语言实现其功能-Mainly used for computing multivariate polynomials C++ language function

实现一元多项式的加减乘除运算和多元多项式的加减乘运算，输入时以字符串的形式输入即可。-Achieve a polynomial multiplication and division addition and subtraction and addition and subtraction multi-polynomial multiplication, input a string in the form of typing.

此代码为多元多项式加减乘化简运算，在vc下运行-Multivariate polynomial addition and subtraction operations by simplifying

简单的两个多元多项式+-×运算 如 (a+b)*(a^2-a*b+b^2)-multi polynominal calculator
