Materializecss and conflicts with jQuery

Question

I’m having a problem here using Materialize CSS and two versions of jQuery. I’m making a onepage site, and I put the Smooth scrolling Effect(I picked up on this site here > http://www.learningjquery.com/2007/10/improved-animated-scrolling-script-for-same-page-links ) and it uses a different version of jQuery 3.1.1 (in which it uses Materialize uses). So when I leave jQuery 3.1.1 active in the code, the Materialize JS effects work, but when I let jQuery 2.1.1 (used by Smooth scrolling) work, Smooth scrolling stops working. I tried using jQuery’s "conficts" method, but that didn’t work either.
