In the video, a person is seen writing numbers on a whiteboard with a pink marker. The person starts by writing the number 3, then writes the number 1, and finally writes the number 2. The numbers are written in a large, bold font and are clearly visible against the white background of the board. The person's hand is steady as they write each number, and the marker leaves a smooth, even line on the board. The video is shot from a close-up angle, focusing on the person's hand and the whiteboard.
