The split environment provided by AMS-LaTeX is used to split a long equation over multiple lines, similar to the multline environment. Unlike multline, however, split allows for alignment using &, and must be used inside another math environment such as equation. It does not add an equation number on its own.

According to the amsmath user's guide, the split structure should constitute the entire body of the enclosing structure (apart from commands like \label that produce no visible output).


	55 &= 1 + 2 + 3 + 4 + 5 \\
	   &\quad + 6 + 7 + 8 + 9 + 10


To use split, import the amsmath package with \usepackage{amsmath} in your preamble.
