Tips for Working with Percentages
- ✓ Always double-check which calculation type you need before entering values
- ✓ For discounts, use the "Decrease by %" option to find the final sale price
- ✓ Use decimal points for precise calculations (e.g., 7.5% instead of just 7%)
- ✓ For grades, use "X is what % of Y" where X is your score and Y is the total points
- ✓ Percentage change shows both increases and decreases - always check the direction indicated
💡 Pro Tip
When comparing prices or calculating discounts, remember that a 50% increase followed by a 50% decrease doesn't bring you back to the original number. The percentages are calculated on different base values, so the results will differ!
