Latex does not go to next line












2















I am working on a document for school, trying to make some equations lines. However, the double dollar command for making equations omits the next line command.



$$

    S(k+1)  &= sum(a[i]cdot a[j] mid i,j : 0leq ileq j < k + 1)\

            &=

$$


I would expect the equation to go to the next line and continue indentation from the = character, however the document shows me this:



enter image description here



I have tried disabling packages but this offers no solution.



When I started working in this document there were no issues, a few hours later it suddenly stopped working correctly.



Any help is very much appreciated.

    $$ should never be used in LaTeX. In your case, substitute them with begin{align*} and end{align*} respectively.

This cannot work: the construct $$ ····· $$ (which anyway is a plain TeX construction and should be replaced in LaTeX with [ ····· ]) is for a one-line centred equation.



For what you want you should use the amsmath align (lines numbered) or align*(unnumbered), with the alignment point specified with an ampersand. For other types of multiline equations, please take a look at the documentation of amsmath, or its extension mathtools.

    For reasons not to use $$ to start and stop an unnumbered displayed equation in a LaTeX document, see Why is [ ... ] preferable to $$ ... $$? For still more information on this subject, see What are the differences between $$, [, align, equation and displaymath?



    Anyway, all you need to do to salvage your code is to replace the first instance of $$ with begin{align*} and the second instance of $$ with end{align*}.



    While you're at it, though, you may want to enlarge the (, |, and ) delimiters, and you may want to either replace : with colon or use double-sum notation. Both options are pursued in the following example.



    enter image description here



    documentclass{article}
    
usepackage{amsmath} % for 'align*' environment
    
begin{document}
    
begin{align*}
    
  S(k+1)  
    
    &= sum bigl( a[i] cdot a[j] bigm| i,j colon 0 leq i leq j < k + 1 bigr) \
    
    &= sum_{i = 0}^j sum_{j = 0}^{k + 1} bigl( a[i] cdot a[j] bigr)
    
end{align*}
