In this video, a man is standing in front of a chalkboard with various mathematical equations written on it. He is wearing a black shirt and holding a piece of paper in his hand. The man is speaking to the camera and pointing to the equations on the board. The chalkboard has several mathematical expressions written on it, including "S = 47°", "RTR = FTR", "68 3/16", "68 1/16", "3/16", "3/8", and "total toe out". The man appears to be explaining the equations and their significance.
