* represents multiplication but why is it written like f*, this makes it look like f has an exponent (in module 6 question no 6) it would have made sense if f*I not f*=I that just complicated things for me.

CSS The text-indent property I do not understand why you would use this when the </br> tag takes the text back to the left hand side of the page, and as soon as I start a new class the first line of text in a paragraph even with a class it imprints onto every other paragraph like it or not. Why is this please?
