Math Made Easy

Professor David Martinez taught calculus at a community college for 15 years, watching students struggle with the same concepts semester after semester. Textbooks were dense, tutoring was expensive, and most students couldn't afford help. He started filming his whiteboard explanations and uploading them to YouTube, expecting maybe his students would watch. Instead, millions of students worldwide discovered his clear, patient explanations. His calculus videos became the de facto homework help for high school and college students across the English-speaking world. His approach - treating viewers like smart people who just need concepts explained clearly - resonated with the frustration students felt toward convoluted textbooks. Today, Professor Martinez has helped over 100 million students understand math. His videos are assigned as homework by teachers worldwide, and his channel generates more income than his 30-year teaching career would have.
