Find the Words

I am a new user and would like to know if I need to purchase an account to create different content? 

Hi

I would like to know where I can find instructions to use Latex arrays and tables.  After entering my code, the slide looked messy.  This is how it looked like after everything was typed.  Each line of text is its own table followed by the box to be filled.
