Description: A dark background filled with white chalk-like drawings of mathematical formulas, equations, and geometric shapes. Prominently featured are multiple instances of 'E=mc²', various circles divided into sections with hatching, graphs with axes labeled X and Y, and other algebraic expressions like 'x = 1/2' and 'q²'. The style mimics hand-drawn chalk on a blackboard.

Description: Bring hilarious classroom sarcasm and mathematical genius humor to your next lecture with this classic math teacher design. Featuring the witty slogan "WHAT PART OF DON'T YOU UNDERSTAND?" written in a bold white varsity slab serif block font layout, this graphic centers a dense white chalkboard cluster of complex calculus equations, integrals, matrices, trigonometry formulas, and geometric graphs. Perfect for math teachers, professors, and engineering students.

Description: A dense, all-over pattern of white hand-drawn mathematical formulas and geometric diagrams on a black background. The layout is chaotic, resembling a chalkboard filled with complex equations, symbols, and geometric shapes like triangles, squares, and coordinate systems. No single dominant shape is present.
