Additive figures
--- Introduction ---
This module contains for the time being 29 visual training activities
of arithmetics (addition, substraction), which can be considered either as
exercises or recreations.
These are all ``drag & drop'' activities, consisting of placing numbers or
expressions into a picture, with geometric conditions on theirs sums. The
first number in the list indicates the number of objects to place. With a
wide variation of styles and difficulty levels in order to meet various
requirements.
