The mathematician is being carried away on a stretcher because he committed the ultimate mathematical sin - element-wise matrix multiplication instead of proper matrix multiplication! In linear algebra, matrices multiply through a specific row-column operation, but this poor soul just multiplied the corresponding elements directly (3×5, 6×4, etc.). That's like putting pineapple on pizza in the math world - technically possible but enough to get your math license revoked. No wonder they're rushing him to the Mathematical Emergency Room!
