Non Inverting and Inverting Amplifiers

Can someone please explain the difference between non inverting and inverting amplifiers for me, all I know at the moment is that the gradient of Non inverting amplifier is usually positive?

I think you mean "gain" rather than "gradient".

An inverting amplifier produces a negative output for a positive input, and vice-versa (i.e. the gain is negative).

A non-inverting amplifier has a positive gain; the output has the same sign as the input.

Hope that helps.
