Hi Clara, you will find a description of MathPackV a pack for mathematics in ST at this link http://www.macqueen.us/smalltalkReport/ST/91_95/SMAL0405.PDF. I bought it some years ago a version for VSE and I do not know if it is still sold. If it not sold at present, I am not sure I can give it to you, but I suppose I can extract the parts interesting to you, on which I worked myself. This package can be very easily ported to Pharo. If you have any problem, please do not hesitate to get in touch with me.

Hi guys, after having exhausting four months of Physics lessons, I decided that would be fun to write a program to deal with Electricity problems :) (Yeah, I'm not a normal person :P) So, I need to make differential and integral calculus, are there any libraries to do so? Or any place that I can take a look at? Thanks in advance! Cheers
