I have a very big equation and using split or multiline is not helping. How do i wrap it and how do i make sure thatRHS of the eqn is always on the right side of equal to ('=') even when line is changed

  m_{12}(\{ \emph{Red},\emph{Blue} \})= K'* [m_{1}(\{ \emph{Red},\emph{Blue} \})*m_{2}(\{    \emph{Red},\emph{Blue} \})+m_{1}(\{ \emph{Red},\emph{Blue} \})*m_{2}(\{ \emph{Red},\emph{Blue},\emph{Green} \})+m_{2}(\{ \emph{Red},\emph{Blue} \})*m_{1}(\{ \emph{Red},\emph{Blue},\emph{Green} \})]

Use aligned:

    m_{12}(\{ \emph{Red},\emph{Blue} \}) 
    = K' * \bigl[ & m_{1}(\{ \emph{Red},\emph{Blue} \})*m_{2}(\{    \emph{Red},\emph{Blue} \}) \\
     + & m_{1}(\{ \emph{Red},\emph{Blue} \})*m_{2}(\{ \emph{Red},\emph{Blue},\emph{Green} \}) \\
     + & m_{2}(\{ \emph{Red},\emph{Blue} \})*m_{1}(\{ \emph{Red},\emph{Blue},\emph{Green} \})\bigr]

    I'd use \mathit rather than \emph – egreg May 3 '13 at 20:06
  • @egreg The italic font is strange anyway, I just copied from the question. – Alex May 3 '13 at 20:08

Have you tried using the align environment?

enter image description here



  m_{12}(\{Red,Blue\})&=K'*[m_1 (\{Red,Blue\})*m_2(\{Red,Blue\})\\
                      &\qquad +m_1(\{Red,Blue\})*m_2(\{Red,Blue,Green\})\\
                      &\qquad +m_2(\{Red,Blue\})*m_1(\{Red,Blue,Green\})]

    using \mathit{Red,Blue} instead of just the words would result in a nicer appearance with respect to intra-word kerning. (the alignment is very nice, however.) – barbara beeton May 4 '13 at 13:11
  • Any easy way to line up the m_1 on the first two lines? – Eric Dec 27 '19 at 11:03
