# Align leads to poor result [duplicate]

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}
\end{align}


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}


• I think you shouldn't use hspace commands within align environments. – NVaughan May 27 '18 at 17:36

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.
• 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
