For multiplication use <code>*</code> or simply space. For exponentiation use <code>**</code> or <code>^</code>. You can add extra spaces around all these, just not between <code>-</code> and an exponent.

One of good choices to write a readable source text is using spaces between factors and no space around exponentiation (the first two examples below).

How to use this template

This template outputs prime factorization in a pleasant form, given a plain-text expression.

For multiplication use *. For exponentiation use ** or ^. You can add extra spaces around all these, just not between - and an exponent.

One of good choices to write a readable source text is using spaces between factors and no space around exponentiation (the first two examples below).
