Arduino to connect +/-10v

Hi all i am having a physical device which iam using with arduino with an input of +/- 10V but the arduino is having only 5v. I need to connect this arduino with this +/- 10V input, please help me whether how can i make it using an Inverting op amp or any voltage adders is usefull and how can i connect ?

You need an opamp circuit that steps down your -10 to +10V to 0-5 V.

do u think which type of op amp i can use for this case can u help me with the circuit?
