We start by breaking down what we mean by the word 'dimension' in math. We take a few examples from 0D to 3D to understand the differences. We then talk about axes - and how they keep increasing as we move up in higher dimensions. These axes divide the planes into 4 quadrants and space into 8 octants. We learn the conventions for signs of coordinates in these octants. We then practice problems on basics of 3D.
