ok its very simple, for that we need to define a block called split like such:

\begin{split} - start of the block

\end{split} - end of the block

yes, please put in both beginning and end bits of this and don't be lazy

after that you can split ines by using \\

you can also align lines by a symbol by using an ampersand (&) in front of it

[math]

\begin{split}

\text{These Lines}&-\text{will be aligned}\\

\text{by the}&-\text{dash symbol}\\

&-\text{shazaam}\\

\text{boogie boogie} &-

\end{split}[/math]

similarly you can use = sign in equations, or whatever it is your heart desires

[math]

\begin{split}

2&=1+1 \\

2&=3+1-2 \\

\end{split}

[/math]

this way you can post

[math]m_{rel}=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}[/math]

which would render as

[math]m_{rel}=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}[/math]

ooh better yet

[math]\begin{split}\Delta P &= \frac{v}{c} \times \frac{E}{2c} \\

2\Delta P &= v\frac{E}{c^2} \\

P' &= Mv - 2\Delta P = \left(M-\frac{E}{c^2}\right)v \end{split}[/math]

[math]\begin{split}\Delta P &= \frac{v}{c} \times \frac{E}{2c}\\ 2\Delta P &= v\frac{E}{c^2} \\ P' &= Mv - 2\Delta P = \left(M-\frac{E}{c^2}\right)v \end{split}[/math]

[math]\begin{split}E^2-(pc)^2&=(m_0c^2)^2\\E^2&=(m_0c^2)^2+(pc)^2\\E&=\sqrt{(m_0c^2)^2+(pc)^2}\\E&=c\times\sqrt{(m_0c)^2+p^2}\\\text{where } p=\gamma m_0v\\E&=c\times\sqrt{m_0^2c^2+\gamma ^2m_0^2v^2}\\E&=m_0c\times\sqrt{c^2+\gamma v^2}\end{split}[/math]

I bet I am not the first person to ask about this, but how do we work around this? Whats up?
