Here is a detailed description of the video: The video shows a person sitting at a desk, focused on writing on a piece of paper. The person is wearing a black hoodie with a white "B" logo on the right chest and a grey beanie. The desk has a wooden top with a blue metal frame. The person is sitting at the desk, facing the camera. On the desk, there are several pieces of paper with writing on them, a black calculator, a red and black pencil, an eraser, and a metal ruler. The person is holding a blue pen in their right hand and writing on one of the papers. The person appears to be deeply engrossed in their work. The background is out of focus, but it seems to be a classroom setting.
