Writing code that way I can understand. But it's kind of useful to be able to read other peoples code and know what it does.

Also, "1 + 2 * 3" is quite obviously 6 and not 9 in languages with operator precedence, I really don't think you need to write "1 + (2 * 3)".

Everything in moderation.

EDIT: hahaha, well I feel stupid. I'm leaving the incorrect answer there because it's too funny not to :)
