STM32F303 op amps

I am a bit confused about the F303 op amps. If they can be used in inverting mode
won't a positive voltage into the minus input result in a negative output voltage?
Of course it won't happen because they are rail to rail opamps.
I need a summing input for two signals so can I use a negative offset like any other op amp to prevent it from trying to go below ground? It just seems wrong
to have a negative voltage connected to a uC
