\begin{equation}
S=\sum\limits_{i=1}^{8}A_i
S=\sum\limits_{i=1}^{8}B_i
S=\sum\limits_{i=1}^{8}C_i
S=\sum\limits_{i=1}^{8}D_i
\end{equation}
Considering the above code, I am so interested to know that how it is possible to print these 4 equations, one per line, instead of all followed in one single line.

Package
amsmath
provides many environments for equations, e.g.:gather
for centering equations by defaultalign
, which allows vertical alignmentsExample:
Equation number in last line
Equation number in the middle
