When I was in 7th-12th grades, my school did something similar. When it came to multiplication, "x" was replaced with a centered dot. I'm stupid. See reply.
The dot is a fairly common one. It has nothing to do with religion, it's because of the ambiguity between x as a multiplication sign and x as a variable in algebra - you don't want to write something like "y = 4xx^2 + 2xx + 1".
