Mysql - And Or

Hi,
I am trying to use WHERE id='10' AND name!='bobby' OR username!='bobby9101'

So pretty much if my database looks like:
rows:
id
name
username

And I want to select WHERE id='10' BUT if name='bobby' OR username='bobby9101' don't return it.
So One field needs to be required, but if one of the others matches, then don't return it.
Is my code right?

WHERE id='10' AND name!='bobby' OR username!='bobby9101'

Code (markup):

 

Nearly there, but I would group the logic into brackets

WHERE id='10' AND (name!='bobby' OR username!='bobby9101')

Code (markup):

 

thanks, +rep added
