In the condensed structure

CH3CH2CHCH double bonded to CHCH(CH3)2
!
CH3

What does it mean when the CH3 is in () followed by the 2?

CH3CH2CHCH double bonded to CHCH(CH3)2
!
CH3
It means the two CH3 groups are attached to the immediately preceding C. If thiws turns out right I have bolded that C atom to which the two methyl groups are attached.
CH3CH2CHCH double bonded to CH<b>C</b>H(CH3)2
!
CH3
That single H is attached to the same C atom, also.

If you look closely you can see that C atom is bold face type.

I have to draw a skeletal, kekule, and lewis structure for this but I am having some difficulty because there is so much going on in the structure. Do you know of any websites that could show me examples of these types of condensed structures?

Here is a page I obtained by searching on 2,2-dimethylheptane. That would be
CH3C(CH3)2CH2CH2CH2CH2CH3
