how it works

three instruments. then two ways up.

first I keep you oriented: a mountain (where you're going), a compass (what you can do now), a next step (what to try, and why). then there are two ways to actually climb. pick one and scrub it from start to summit. this is the app, not a storyboard.

the mountain

where you're going. a summit you can stand on, and how far up you are.

the compass

what you can do right now. every concept in plain words, honestly.

the next step

what to try now, and the reason you're stuck. one thing, no menu.

the two ways up
the next step
a guided climb

laid out after watching you try, reshaping as you go. the problem comes first; content only when you've earned it. it skips what you already know.

the wander
follow a thread

it asks before it answers, cites its sources or stays quiet, and every answer ends in a try-this. the thread maps itself and joins your climb. nothing wasted.

today I hand you a problem, not a lecture.
a circle: x² + y² = 25. find dy/dx at the point (3, 4), without solving for y first.
show your work. I watch the approach.

last time you solved for y. the short way is hiding in the question.
two ways up. I switch between them when I see you need it.

you don't pick one and commit. a next step can spill into a wander, a wander can become your next step. the map keeps it all honest.
