A close-up image depicts a white, blue-lined notebook page filled with handwritten mathematical equations in blue ink. The equations involve algebraic expressions with variables such as x, a, α, and β, alongside exponents, square roots, and cubic roots. The Bulgarian word "има" (meaning "has" or "there is") is legible within the mathematical context, indicating a Bulgarian educational environment. A yellow wooden pencil is partially visible on the left side of the frame. The notebook rests on a light-colored wooden desk surface. In the out-of-focus background, a book or notebook with a green cover is present. This scene depicts a study or classroom setting within an educational institution in Sofia, Bulgaria.
