Blackboard with Math Equations and Illustrations

A classic blackboard serves as a canvas for mathematical illustrations and conceptual thinking. Featured prominently are the equation 'a + b = c', a labeled line segment, and a pair of x-y axes, all drawn in chalk. In the bottom right corner, a hand-drawn lightbulb illuminates, symbolizing the spark of an idea or understanding that often accompanies learning and problem-solving.
