Loading libraries in Dr Scheme-Collection of common programming errors

I am working through SICP using Dr Scheme.

How do I load external libraries in Dr Scheme? Say I want to use Math library then how do I ask Dr Scheme to load the particular library?

I tried with the following: (require (lib “math.ss”))

Got the following error: reference to undefined identifier: require

I have chosen R5RS as the language.
