CloudLabs Vector subtraction vs Math Lessons by Voice

This lab has a Cartesian plane available where the user can draw five vectors, use the head-tail graph method, and find the resulting sum. You can also draw a vector of equal magnitude, but in the opposite direction. The goal of the lab is to find the magnitude of the vectors, the angle, and the components in X and Y.

Math you hear and speak. Listen to a problem, solve it in your head and say the answer out loud — no tapping and no typing. Math by Voice turns mental-math practice into short, hands-free sessions you can do in the car, on a walk or anywhere you want less screen time. Choose activities with voice commands, start with addition, and unlock new topics step by step. The app combines focused practice with a structured course of 10 interactive lessons. The 10-lesson course progresses from mathematical foundations through arithmetic, fractions, formulas, equations, powers, and quadratic equations. Each lesson combines narration, visual explanations, interaction, and saved progress. Features: • voice navigation and spoken answers — no buttons needed; • addition, subtraction, multiplication, and division; • squares, roots, fractions, and equations; • a structured course of 10 interactive narrated lessons; • mathematical terms and definitions; • difficulty levels, timers, and configurable sessions; • progress, streaks, and performance statistics; • English and Russian languages; • support for iPhone and iPad. Microphone and speech-recognition permissions are required for the voice-first interface. Recognition is provided by Apple and may require an internet connection in some situations. The first lesson and addition practice are free. A one-time Full Version in-app purchase permanently unlocks the remaining lessons, practice activities, terms, and Mission to Planet X.
