How to add commons-math library in Android Studio

I am trying to import common-math library to my Android Studio project. I placed the file commons-math3-3.6.1.jar file in libs folder and in the gradle file I have this line:

compile 'commons-math3-3.6.1.jar' but I get this error: `

Error:(32, 0) Supplied String module notation 'commons-math3-3.6.1.jar' is invalid. Example notations: 'org.gradle:gradle-core:2.2', 'org.mockito:mockito-core:1.9.5:javadoc'.

Can anyone tell me what I have to do?
