Percentages show up everywhere: discounts, marks, tax, and growth.

## Common percentage use-cases
### 1) Find X% of a number
Example: 15% of 2,000

$$2000 imes rac{15}{100} = 300$$

### 2) Percentage increase/decrease
Example: Price goes from 800 to 920

$$rac{920-800}{800} imes 100 = 15%$$

### 3) Reverse percentage (find original)
If 1,120 is after 12% tax:

$$ ext{Original} = rac{1120}{1.12}$$

## How the calculator helps
