How do you recognize the difference between inverting and non-inverting op amps?
I'm looking at different schematics and they pretty much look like the same to me.
Or does that depend on the output values after calculating them?

If schematics all look the same to you, you need to look at them closer.
Look at some simple schematics, such as the ones in the reference for basic inverting and non inverting configurations, diff amp, summing amp, voltage follower, and others.
Study those and the bit of math that applies to each one.

yes, the inverting and non-inverting op-amp are almost the same. They are pretty much almost built the same way in a circuit. An inverting op-amp becomes non-inverting buy simply applying the input signal to the + of the op-amp

usually if the input voltage source is on the + sign the op-amp is non inverting.
if the input voltage source is on the - sign of the op-amp, it is inverting.
it is usually best to just derive the equations and this will tell you for sure whether it is inverting or non-inverting.
