Normally, when you have a long equation, you can split it on two lines. Suppose that $a$ and $b$ are very long expression. Then, for example:
$$ x = a - b$$
can be rewritten as
$$ x = a + $$ $$\quad-(b)$$
I use $+$ and $-$ to maintain a consistency. What do I have to do when using boolean operator? For example, I have to split into two lines the followings:
$$x = a \wedge b$$ $$x = a \vee b$$
Which is the correct way to do this?
