ObachtMathe - Invidious

ObachtMathe

Hallo zusammen, egal ob du gut oder schlecht in Mathe bist, hier bist du genau richtig!
Auf diesem Kanal stelle ich einen Teil meines Mathematikunterrichts für Schüler und jeden Interessierten zur Verfügung. So können Themengebiete wiederholt und geübt werden. Jeder darf diese Videos benutzen und verlinken!

Jedes Themengebiet wird in einer Playlist geordnet, so dass die einzelnen Themen aufeinander aufbauen.

Zu jedem Thema gibt es nicht nur die Erklärung, sondern auch ein extra Video mit Übungsaufgaben mit Lösungen. Bei den Erklärungen gehe ich auf Tipps und Tricks, häufige Fehler, "gemeine" Aufgaben und Ähnliches ein. Am Ende einer Playlist gibt es eine Zusammenfassung des Themas.

Fertige Playlists haben einen Haken ✔

Möchtest du mich unterstützen, dann darfst du mir gern ein Getränk deiner Wahl hier spendieren:

Vielen Dank!
Natürlich freue ich mich auch über jeden Like und jedes Abo!
