Hi my question is How does the pH relate to the concentration of Hydrogen ions?

what I think is The relationship between the pH and the concentration of Hydrogen ions is that the -log of the hydrogen ion concentration is equal to the pH, but this doesn't seem right at all.

The pH is $$pH = -\log[H^{+}]$$. So you are correct.

I thought there would be a more complicated answer

Nope. See pH definition and pH scale for more details - but they won't change what courtrigrad have already wrote.
