Welcome to XO Math! Calm. Clear. Step-by-step. This channel features instructional videos in Algebra, Trigonometry, Precalculus, and Calculus I & II with plans to expand into more content soon! I'm a community college professor and former AP Calculus AB/BC teacher, here to help students learn math and maybe even love it. I’ve been making video lessons for over 10 years for my own students, but was too nervous to share them publicly. As a woman of color in mathematics, I haven’t always seen myself reflected in the field but my students encouraged me to go for it. That’s part of why I created XO Math: to share clear, calm, step-by-step lessons for everyone. I’ll be updating existing videos during school breaks and adding new playlists focused on popular topics. Please reach out of there is a topic or course you are looking forward to seeing. 💙 Visit www.xomath.com for an organized list of videos and extra resources. XOXO, Professor Morales Why XO? Those are my son’s initials. 💙
