You cannot type -module(math1). directly into the shell.
make a file (math.erl) containing the lines "-module(math1). ..." etc.
then compile the module in the shell like this:

> c(math1).

This will compile the code in math1.erl, then you can run the
functions in the shell
> math1:funcname(...) etc.
