Hi there,

The answer to your first question is the asterisk (*). Use the asterisk everytime you want to remove the numbering in the different parts in LaTeX. Something like this:

  1. \section*{question 1}


My answer to your second question might not be the best suitable, but it works. You can use the \text command in the math mode to add some space.

  1. $ a \text{} = \text{} b + c $


Hope this helps. Cheers

For your second question:
The command:
creates a space in the document

Hi futuresimon. Welcome to the forum!

I cannot recommend this. Although this does insert a space it misuses the macro for emphasis. There are better alternatives:

  • \space inserts a simple inter-word space
  • \nobreakspace inserts an inter-word space which prohibits line-breaking. The shortcut for this is ~.
  • \hspace{1cm} inserts a horizontal space of 1cm.

There are more options. Which one's the best solution is hard to guess since the question is rather vague.

For the first question nowadays I'd suggest using a dedicated package for problems such as probsoln, exam or exsheets.

Best regards
Clemens
