I have a few suggestions for you to get prompt help here:

- Use unique and descriptive topic titles.
- Use proper bracketing symbols or better yet use to make your questions unambiguous.
- Show you work so the helpers here know exactly where you are stuck.

Interesting. Soroban's interpretation of what sscgeek wrote is quite different from ebaines' interpretation.

I would say that Soroban's interpretation is correct (paretheses needed in the equation), though I can see how ebaines could interpret the equation the way he did without the parentheses.
