Correct way to align equations equal to zero












2












$begingroup$


This is a question related to formatting. I have an expression that is equal to zero; I work over this expression to obtain a final relation as shown below:



$$begin{align*}
0 & =int_{V}nablacdotmathbf{A},mathrm{d}V\
& =int_{S}mathbf{A}cdot dmathbf{S}\
& =int_{S}mathbf{hat{n}}cdotmathbf{A},dmathit{S}\
& =left(mathbf{A}_{i}-mathbf{A}_{e}right)cdotmathbf{hat{n}}
end{align*}$$



My question is: is it correct formatting to leave the zero in the left hand side? I have searched for answers but I could not find it. Thanks in advance.

    I see nothing wrong with that.

    I've seen many such calculations. The only other way to format it that would look natural to me would be to reverse the entire calculation, starting with $left(mathbf{A}_{i}-mathbf{A}_{e}right)cdotmathbf{hat{n}}$ and concluding with $0$. But if the natural flow of your argument in its context runs the direction you've shown, there is nothing wrong with it.

    That looks correct to me, but... I feel like this question should be on Meta instead. On the other hand, the notation tag description does mention usage...
