How Can You Express Complex Numbers in LaTeX?

I know all the numbers of a real part of an equation is given as

How do you express your complex part in the same form?

It's actually

$$\mathfrak{Re} \, \mbox{and} \, \mathfrak{Im}$$

or $$\Im$$ (??)

Ah right thank you. I wasn't sure at all. I have never used these in latex. Thanks
