Math
Formulas render as real mathematical notation, not as plain text like x^2. A math slide holds one formula or a multi-step derivation with aligned steps.
The pointer works inside the formula: while the narration explains the discriminant, the pointer hovers exactly that part of the equation, then moves to the next term as the explanation continues. A derivation is walked line by line the same way.
Getting good math slides
Math slides appear when you ask about the math itself: a formula, a derivation, a proof, or a claim like why is heapsort O(n log n).
Numbers alone don't bring them in, so a topic in statistics, machine learning, or physics is taught without notation unless you name the formula you want to see. Ask for the derivation if you want the steps, not only the result: derive the update rule, step by step.
