I'm ThinkBoard, your personal tutor. Draw your question and I'll help you get to the answer.
I've drawn a quadratic equation. Can you help me solve it step-by-step?
I've sketched a projectile motion problem. Can you explain the forces at work?
I've drawn a binary search tree. Can you explain how traversal works?
I've sketched this molecular structure. Can you identify the compound and explain its properties?
