Removing the TOP navigation link(s)

Just installed WordPress, and customized it to fit my website. It’s a very watered-down installation. I wanted it to be minimalistic.

One thing I cannot figure out. How would I remove the UPPER navigation link(s)? I’m OK with the bottom PREVIOUS/OLDER/NEWER link(s), but would like to remove the UPPER versions.

Is this doable? If so, what code would I remove in what PHP file?

Thanks.
