Fix SyntaxErrors in compound expressions

[mehwar]

The additional parentheses eliminate SyntaxErrors similar to Appendix A that surface when running the default React Native iOS app with Node v5.1.

Appendix A

Your added parens change the meaning of the code. I am fairly sure that the code is valid JS as-is – perhaps you can look at the transformed source to see what happened to it?

Good catch... I'll do some more digging on what's actually going on.

Aside: I tried changing the parens in a way to keep code meaning constant (put it around on the other side to wrap the multiplication operator) and I seem to run into the same SyntaxError as noted in Appendix A :/.

What is Appendix A, sorry?
