This chapter presents an explanation of the divergence and c
on-
vergence of infinite series through the building block probl
em. The chapter
simultaneously expresses the fact that mathematics is not j
ust about manipu-
lating complicated numerical formulae but is also a field in w
hich logical ways
of thought are acquired. It is emphasized that in order to ove
rcome univer-
sity students’ aversions to mathematics, lecturers must po
ur their energies into
developing study materials taken from topics relevant to st
udents.
