#Each type has things you can do with it (*, % etc)
#Soon we'll see types that are not numbers, and things
#you can do with them.  Eg "strings" of characters.

#Type conversion
#sometimes you need to convert to a different type.
#there are functions to do type conversion:
int(7.0)
int(7.99999)    # Chops off the fractional part.
