Why are the 2 input terminals of an op-amp are called as inverting & non-inverting terminals?

Because if we give input to one input means that will produce the same phase output where as the other(Inverting) pin produce 180 degree phase shifted output.

An input applied to the inverting terminal of an Op Amp provides an amplified output which is 180 degrees out of phase with respect to the input, whereas the non-inverting terminal input provides an output which is in phase with the input.

opamp (operational amplifier)is a direct coupled high gain amplifier usually consisting of one or more differential amplifier

The differential amplifier can perform all the arithmetic operations such as addition subtraction even integration so need operational amplifier but basically it is a directly coupled high gain amplifier which amplifies the difference between the voltage applied at the inverting and non inverting terminals and it can be said that opamp amplifies the terminal potential difference.

A high Input at inverting terminal with respect to other give a inverted output where as a high input at non-inverting terminal gives the same as output
