A man is writing on a blackboard in a classroom

A man is writing on a blackboard in a classroom. He is wearing a blue shirt and dark pants. The blackboard is covered in white chalk writing, including numbers and symbols. The wall behind the blackboard is a pale tan and has streaks of black chalk on it. There is a window in the upper left corner, but the view outside is obscured. The floor is a light brown concrete and there are two beams of light on the floor. There is an unidentifiable object to the left, which appears to be a metal table with wooden slats. The scene is likely in a school or educational setting. The classroom is located in Al Kamlin, Sudan, at coordinates (latitude: 15.075, longitude: 33.188).
