# As seen in [1], what is enclosed in .(…) is replaced by its value (0.5)
# As seen in [2], I can introduce symbols, eg. that of fraction (1/2)
# As seen in [3], with * I introduce a small space
# As seen in [5], I can introduce the product symbol with %.&
# As seen in [4], I can introduce the symbol "×" with %*&
# π and square root are introduced in the usual way (see [6])
#
# With "bold" I have the text in boldface (see [7])
#
# ~  introduces a blank space, scriptstyle  types smaller characters (see [8])
