垂直数学是否可以作为编码复杂方程的方式，如下：
{
\\\I want to vertically add line one to line two, and then show it is equal to 2(phi-1) on line three, but I can't find the way to add two stacked equations which use pi, phi or the value of e and get invalid equation messages
\\\
line one: [pi-1/2-(phi-1)-(e-1-1/2)]*2-1=0.61055367276
line two: [[pi-1/2-[[pi-1/2-(phi-1)-(e-1-1/2)]*2-1]-(e-1-1/2)]*2-1]=0.62551430473
line three: (0.62551430473+0.61055367276)/2=0.61803398874
phi-1=1/phi
phi-1=0.61803398875
1/phi=0.61803398875
π, Σ and Φ=0 as,
1/2-1=-1/2
}
这种编码方式太长了：
