Hi! I’m Number Ninja Dave, and my goal is simple: to help you crush your precalculus and calculus math classes. I’ve been there—that feeling of being stuck on a tough problem or knowing you're just too slow at mental math. It's frustrating, and it shouldn't be that way. That's why I created this whole system. It's built from the ground up to actually work for you, no matter what you're struggling with.
This isn't just about giving you a few tips; it's about a complete mental shift. We start with the Number Ninjas Math Game, a fun and fast-paced way to get your brain thinking faster than a calculator. I've designed it to build your foundational math skills so quickly that those easy questions become second nature.
For the harder stuff, that's where my Precalculus and Calculus Youtube videos come in. I dive deep into tricky topics and walk you through them step-by-step. I've covered everything from taking the first steps into derivatives and integrals to getting ready for a big test with my AP exam prep videos. I even have videos dedicated to showing you the common mistakes to avoid so you don’t lose points on your homework or exams. It’s all here to help you get ahead, feel confident in your abilities, and hopefully, even enjoy your journey in becoming a true number ninja. Let's get to it!
