Answer 2

Ordinarily a parenthesis (pl: parentheses) introduces a term or clause that modifies whatever precedes it. It would be preceded by a space and followed by whatever would otherwise follow that term in the absence of the parenthetical remark (e.g., a space, comma, or period).

In mathematics, science, marketing (there's a strange set of bedfellows!), and in certain abbreviations, a parenthesis may be part of a term. As such it serves purely as a character rather than having the functional role of introducing a modifier. It would be as incorrect to insert anything before the parenthesis-qua-character as it would be to put arbitrary spaces within any word.

Thus, preceding a parenthesis (or opening bracket of any kind, such as "[" or "{") by a space provides a clear and well-understood mechanism to distinguish these two uses. For example, we would read "IPhone(5MP)" as being the full name of a particular kind of IPhone, whereas "IPhone (5MP)" would refer to something whose name is "IPhone" which happened to have the "5MP" property. That is a subtle distinction in this case, but perhaps it's strong enough to permit a reasoned choice concerning the usage that best conveys the intended thought.
