Wrap the math in a try/except block such as:

# Handle the zero-division plus maybe some others:
exceptions_to_handle = (ZeroDivisionError,)

try:
	# do the math here
	result = eval(my_math)
except exceptions_to_handle, e:
	# gracefully handle here
	result = str(e)
# show the result in the calculator here
print result

... or something like that. The point is you need to handle the zero 
division error while not handling other, unexpected error conditions.
