The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.

线性的威力是,一个方程，如果它是个线性方程，那么我就不用再去解他了。

System of linear equations. What are the equations here? Well, I could say, you know, the number of pigs plus the number of 20 chickens equals 20, right? Because we've got 20 heads. And then what else do I have?

如何解决这个问题呢？,用线性方程式的办法来解决，等式是什么呢？你应该知道,猪的数量加鸡的数量等于,对吧？因为我们有20个头？

Again, I'm not going to spend much time on this, of the ith asset is the regression coefficient when you regress the return on the ith asset on the return of the market portfolio.

再强调一次，我不打算花太多时间在这个等式上面，但要注意的是当你想将市场组合收益，but，the，β,回归到第i资产收益中去,第i资产β系数是线性回归方程的,回归系数。
