# Aligning parts of equations

So this is a continuation of my previous question but I didn't know if I should edit that post and ask a new question or just post a new question entirely. Anyway, I have this bit of latex:

\begin{align*}
C_{in-nand3} & = \frac{5.493 * 1.21739}{3.3098} = 2.02 \rightarrow & \frac{2.02}{2.75} = .735  \\
C_{in-nand2} & = \frac{(2.02 + 12.97) * 1.21739}{3.3098} = 5.514 \rightarrow & \frac{5.514}{2.75} = 2.005  \\
C_{in-nand1} & = \frac{5.514 * 1.21739}{3.3098} = 2.0279 \rightarrow & \frac{2.0279}{2.75} = .7374
\end{align*}


And that gives me:

But what I really want is the answers to the first equation to be centered down a middle column. So for example, I want =2.02-> to be shifted to the right and aligned with all the following values such as =5.514-> down a column. I tried adding a & before the =2.02 but that gave me:

Which is not what I want, that is shifted waaay too much.

Have you tried using $$...$$? –  cryptic0 Mar 28 '13 at 16:50
@cryptic0 do I have to wrap $$...$$ around every single line? Because I just posted 3 lines of equations, it's actually much more than that –  Richard Mar 28 '13 at 17:08

perhaps this is closer to what you want?

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{alignat*}{5}
C_{in-nand3} & = \frac{5.493 * 1.21739}{3.3098} && = 2.02 \rightarrow{} & \frac{2.02}{2.75} & = .735  \\
C_{in-nand2} & = \frac{(2.02 + 12.97) * 1.21739}{3.3098} && = 5.514 \rightarrow{} & \frac{5.514}{2.75} & = 2.005  \\
C_{in-nand1} & = \frac{5.514 * 1.21739}{3.3098} && = 2.0279 \rightarrow{} & \frac{2.0279}{2.75} & = .7374
\end{alignat*}

\end{document}


edit: the question Aligning equations with text with alignat addresses a similar problem.

Okay this worked, thanks a lot ! –  Richard Mar 28 '13 at 17:15
Maybe you could mention a link to the question Aligning equations with text with alignat and I'll delete my almost identical answer ? –  Vincent Nivoliers Mar 28 '13 at 17:26
@VincentNivoliers -- done. thanks for the suggestion. –  barbara beeton Mar 28 '13 at 19:38
