Can any one here teach me $${\LaTeX}$$ ?

Also, just in case you haven't heard this yet, if you seem some fancy $\LaTeX$ on OS, and you want to know how it was typed, right click on the math, select "Show Math As" and click on "TeX Commands." This will show you exactly what you need to enter in the equation editor.

For practice :)$$\begin{matrix}
   a\uparrow\uparrow b & = {\ ^{b}a}  = & \underbrace{a^{a^{{}^{.\,^{.\,^{.\,^a}}}}}} & 
 
\  
  
    & & b\mbox{ copies of }a
  \end{matrix}$$
