A close-up of the green chalkboard with a new equation. The white chalk text is centred: 'four' on the top line, '+ five' on the middle line, and '= ?' on the bottom line. The lighting is consistent and even, highlighting the dusty texture of the chalk. No people are present in the frame. The mood is quiet and educational.
