Top contributors over the past week! 🙂


It’s refreshing to see a non-male-dominated name list. Expii’s vision is to provide a variety of voices explaining each topic, setting learners free to choose their preferred style.

Ultimately, we hope to welcome a wider audience to math and science through diverse content authors, video stars, and role models. Thanks to all for contributing your voices to the world’s collection of interactive lessons on math and science! 🙂
