Lessons that teach with you, not at you.

Flax turns each topic into a guided conversation. Students answer one manageable question, get immediate feedback in plain language, and keep building until the idea makes sense.

One clear step at a time

Short explanations and focused questions keep a hard topic from feeling overwhelming.

Help that adapts to the answer

Hints and follow-up questions respond to what the student understands right now.

Understanding before moving on

Every lesson checks the idea in context, not just the final answer.

NOTICE
Start with what is happening to the group.
What should we do first?
3(x + 4) = 27
Divide both sides by 3
Exactly.
Dividing by 3 leaves x + 4 = 9. Now the variable is one step away.
YOUR NEXT STEP
x + 4 = 9

How it works

Practice, get stuck, then get un-stuck on the exact thing you missed.
01

Practice a skill

Work through hand-picked problems, Grade 7 through AP Precalculus, plus AMC 8. Every question is written by hand and arranged in an easy → medium → challenge ladder.
02

Get stuck? Scan it

Missed a multi-step problem? Snap a photo of your actual paper. Flax reads your work line by line and finds exactly where your logic slipped.
03

Fix the real gap

You're routed to a short lesson on the foundational skill underneath the mistake, so the next attempt goes differently.
ADAPTIVE PRACTICE

Remembers what you forgot

Once Flax spots a weak spot, it works matching questions back into your normal practice, so the gap gets tested in context instead of becoming a separate drill you'll want to skip.
