[Tex/LaTex] Default LaTeX font for all commands and definitions


What is the font that LaTeX uses as default for: the notmal text, the \bfseries, the \itshape etc and all commands and definitions in the table 43 at page 131 of this guide?

I have found some fonts in this directory: C:\texlive\2011\texmf-dist\fonts\opentype\public\lm. I suppose that the default font for math is lmmath-regular.otf, right?

The default font set for TeX is Computer Modern, designed by Knuth specifically for TeX use.

So the 10pt roman font is cmr10, the italic cmti10 bold (extended) cmbx10 etc.

For mathematics the situation is more complicated as there is not a single font, different characters come from different fonts. The main math italic is cmmi10 The main math symbol font is cmsy10 with big brackets etc coming from cmex10.
