10 INTERACTIVE LESSONS

The course progresses from counting and arithmetic through fractions and formulas to equations, powers, and quadratic equations. Lessons combine spoken explanations, visual material, questions, and saved results.

VOICE PRACTICE

Choose an operation, difficulty, number of questions, and answer time. X-PlanetMath reads each problem aloud, listens to the spoken answer, and provides immediate feedback.

WHO IT IS FOR

• children learning mathematical foundations;

• students practicing mental arithmetic;

• adults maintaining calculation speed and concentration;

• learners who find spoken interaction more convenient.

Microphone permission is required for voice features. Offline speech-recognition availability depends on the device and installed speech service.

All current learning modes are available free of charge during early access.
