- I have never posted before. But, I had a question:

What is the mathematical process of "opposite," using the general definition of the word?

What is opposite in Mathematics?

I argued with my engineering brother and his pal that "inverse" is indeed "opposite" if you use the general concept of "opposite." My brother claims that the idea of opposite in mathematics only means returning to null.

Opposite: 1.) Having a position on the other side. 2.) Diametrically different.

Am I totally wrong? Or is the idea of opposite not very applicable?
