the arabic numbers

Dear Dr Mohammed
concerning the lecture
the arabic numbers are not those we use now, we use now the indian numbers.
the arabic numbers are those being used in Europe at the time.
so arabic numbers 1,2,3,4

as the Khawarzmi innovated the new numbers (the arabic numbers, which are now used in europe), he did not make beutiful figers, but he draw them with a concept.
it depended on the number of angels in each figure:
so O has no angels, referes to nothing
1 has one angel (the upper one, as the German 1 not the english oone), 2 has two angels, 3 has three angels and so on
