A good answer might be:

24 / 2  - 8
------
  12    - 8
  ---------
       4

When there are two (or more) operators of equal precidence, the expression is evaluated from left to right. Examples:

2 * 7 * 3 
-----
  14  * 3
  -------
     42

4 - 2 + 5
-----
  2   + 5
  -------
      7

Usually it doesn't matter if evaluation is done left to right or in any other order. In algebra it makes no difference; But with compuer math it sometimes makes an important difference. This will be discussed in a few pages.
