Calculating moment of inertia for a uniform rod of mass

[Luminous Blob]

I have a uniform rod of mass M, which rotates about one of its ends, and a point mass equal to the mass of the rod is added to the other end.

To calculate the new moment of inertia, do I just need to add the moment of inertia of the rod and that of the point mass together?

i.e. I = (MR^2)/3 + MR^2 ?

Any help would be much appreciated.

Yes you add them together, but make sure you add them together with respect to the same axis. Remember the parallel axis theorum.

Cheers for that.
