align vs equation
Is there any reason why I should use
equation when I
align seems to produce the same output?
The reason I am asking is that I like solving math using LaTeX. Sometimes I write a single equation using the
equation environment, but later realise I need to include more equations aligned to the first in that same environment. Then I need to change the
and include the
&s as appropriate.
I am thinking then: why not always use align, maybe even including the
& before the equal sign, just in case I need to include more stuff there later? If they behave the same, and one is more flexible, why use the other at all? Or are there differences and reasons why I should avoid using
align when there is a single equation?
