Why Build a Calculator?

🚀 Did You Know?

In 1969, the Apollo 11 spacecraft landed on the moon using a computer less powerful than your phone. That computer? Essentially a very sophisticated calculator.

💼 Real Talk

Every app you use—from Uber calculating fares to Netflix predicting what you'll watch—is built on the same fundamentals you're about to learn. Calculators teach you how computers think: take input, process it, give output. Master this, and you've mastered 80% of programming logic.

🎯 What You'll Unlock

  • Input/Output: The foundation of ALL programs
  • Data types: Why "5" + "5" = "55" but 5 + 5 = 10
  • Functions: Write code once, use it forever
  • Error handling: Make your programs bulletproof

Your Quick Win

🎯 Quick Win: You'll have working code in the next 10 minutes. No joke.
