Mathematics are important to astronatus and were used occasionally in Gravity.

Role in Gravity

Use by Kowalski

Matt Kowalski does some quick calculations to discover that the debris, moving at 50,000 miles per hour, will be circling back around the Earth in 90 minutes. 

He likely used algebra here. 

Use by Stone

Dr. Ryan Stone, while drifting towards the Tiangong station and using a Fire Extinguisher as a makeshift thruster, is unable to get her trajectory correct. She puts the extinguisher in between her legs and uses some quick angle measures to calculate 180 degrees to the station and blast in a straight line. 

She used geometry here.
