Treating the #*# symbol as multiplication, the given expression makes no sense

Explanation:

If #-3*12color(red)(-* )18...# is meant to be interpreted as
#color(white)("XXX")-3xx12color(red)(-xx)18...#
then either the #color(red)(-)# or the #color(red)(* )# should be omitted
or some additional value needs to be inserted between these operations.
