Section 1.6 of the NumAnalysis pharo book needs to be revised for Pharo

Section 1.6 is on page 17 here: http://files.pharo.org/books-pdfs/numerical-methods/2016-04-NumericalMethods.pdf

and for the profiling newbies there is a nice chapter on deep into pharo:

Could be a fun exercise for students of Pharo ;)
