Common Challenges & Solutions
Every beginner faces obstacles. Here's how to overcome them:
⚠️
Numbers are too big to imagine
Solution: That's normal! Use comparisons: 'Light could go from New York to Los Angeles and back 60 times in one second.' Break big numbers into smaller, relatable chunks.
⚠️
Calculations are confusing
Solution: Use a calculator and go step-by-step. Write down each step. Check your work by asking: 'Does this answer make sense? Should it be bigger or smaller?'
