From Zero to Hero: Mastering Percent Change Calculations!

Want to show the world how much you've improved (or how much things have changed)? Calculating percent change is your superpower! It's a simple yet powerful way to express relative changes in values over time.

Here's the secret formula:

**Percent Change = [(New Value - Old Value) / Old Value] * 100**

Let's break it down:

1. **Find the difference:** Subtract the old value from the new value.
2. **Divide by the original:** Divide the difference by the *old* value. This gives you the decimal change.
3. **Multiply by 100:** Multiply the result by 100 to express it as a percentage.

**Example:** If your website traffic went from 1000 visits to 1500 visits, the percent change is [(1500 - 1000) / 1000] * 100 = 50%. That's a 50% increase!

Whether you're tracking sales growth, stock market fluctuations, or even your personal fitness progress, mastering percent change is a valuable skill. Go forth and calculate!
