That doesn't really change what I said, actually. While in some languages you can use "+" to mean string concatenation as well as addition, if the language is strongly typed, it will choose which operation to do based on the types of the arguments. And you may need to cast things anyway, such as if you want to concatenate a number's string representation with a string. I've had to do such casts in Python.

Sure. You're running completely different functions for int+int and int+string, it just so
happens that the two functions have the same name. They don't need to have anything in common
other than the name.
