What I’ve read online says that Vector art uses math to make the image scale better but isn’t ‘math’ used in Pixel art in, say, Photoshop as well? I’m having trouble wrapping my head around how the math might be different when creating a line in Photoshop vs Illustrator for example.

Raster art (pixel-based graphics) stores image information as information about pixels. ‘This pixel in this place is this colour’, basically, over and over again to build up the whole file. Vector art stores image information as vectors – basically lines with thicknesses and curves and so on. That means it can be scaled without becoming fuzzy – the computer just redraws the line. A raster image has no information about ‘lines’; it’s our human brains that figure out where the lines in it are – so when it’s zoomed in, the computer program has to either make each pixel bigger or try to guess at what the pixels ‘would be’ if there were more of them.
