Can I Code If I'm Bad at Math? (Spoiler: Yes, You Can!)

Image

Am I screwed?” The short answer? Nope. Not at all. Coding ≠ Math Class Here’s the truth that nobody told us in school: You don’t need to be a math genius to be a good coder. In fact, most web developers, app creators, and even software engineers barely touch “hard” math in their day-to-day work. You’re not solving calculus problems. You’re building cool stuff.
