Question: User: Create a 9:16 vertical AI math solution video. Show a realistic hand holding a pen and writing the calculation step by step on white paper. At the same time, add a clear AI voiceover that SPEAKS and EXPLAINS every step while the pen is writing. Voiceover: “Let the number be X. We know that 25 percent of X is equal to 50. So, 25 divided by 100 multiplied by X equals 50. Therefore, X equals 50 multiplied by 100 divided by 25. So X equals 200. The correct answer is B, 200.” Synchronize the AI voice perfectly with the pen writing. The pen must visibly write each equation step by step. Do not use typing animation, slides, or a talking avatar. End with the pen writing: “Correct Answer: B) 200”
