代数方程,即由多项式组成的方程。有时也泛指由未知数的代数式所组成的方程,包括整式方程、分式方程和根式方程。 例如:5x+2=7,x=1等。代数,把algebra翻译成代数,就是用字母代替数的意思,继而推广。随着数学的发展,内在涵义又推广为用群结构或各种结构来代替科学现象中的各种关系。也就是说“代数”本质是个“代”字,通过研究各种抽象结构“代替”直接研究科学现象中的各种关系。

I want to show you how easy it is to change the code. But, notice, once I've added this I actually have a problem. This is now an under-constrained problem. I have more unknowns than I have equations.
