Question

Answer 1

If you want simple math calculations, then I would look at views calc. Views PHP has some great uses for quick testing, but it is generally assumed that if you need Views PHP you should write your own module. You can also get a good discussion on this issue at: https://www.drupal.org/node/1219356.
