Simple interest calculates fixed percentage growth on the original amount.
Why Humans Invented Interest Systems
As lending money became common, people needed mathematics to calculate repayment fairly.
Trade and banking required systems for:
- loans
- savings
- borrowing
- investment
This gradually led to interest mathematics.
