I have two align environments which do not quite lead to a good looking result, and I don't know why. To the best of my knowledge, I did not alter anything about the alignment, and the problem also occurs when I copy the equations in a completely empty document.

How can I achieve a the "right", aesthetically pleasing typesetting of those equation?

Right Align

I do not understand why the rightmost term is aligned to the right. And I also think that the position of the = is wrong.

\begin{align}
A \qquad &\longrightarrow \qquad B &= C \\
AA \qquad &\longrightarrow \qquad BB &= ABCDE 
\end{align}

enter image description here

Huge Space

I'm not sure why it introduces such a huge space before the rightmost term. 

\begin{align}
A &= 
\begin{bmatrix}
b
\end{bmatrix}
&= 
\begin{bmatrix}
C + D
\end{bmatrix}
\end{align}

The third column with =C is right aligned but you want it left aligned so put it in the fourth column so use &&=C It might also might look better without the \qquad which is forcing the arrows to have excessive space.

  • "The third column is..." - Is that a general definition in LaTeX, or is there a specific reason for that inside my code? – Michael May 27 '18 at 17:46

    it's a general feature of AMS alignments which are designed for a=b c=d displays so right align to the first =, left align to the =, right align to the second =, left align to the second =. – David Carlisle May 27 '18 at 18:50
