Our Mission
Our mission is to provide a free, accessible, and easy-to-use scientific calculator that works across all devices. We believe that everyone should have access to tools that help with mathematical calculations, whether for education, work, or everyday life.
The History of Calculators
Calculators have a rich history dating back thousands of years:
- Ancient Times: The abacus was one of the earliest calculating tools, dating back to around 2000 BCE.
- 17th Century: Mechanical calculators were invented, such as Blaise Pascal's calculating machine in 1642.
- 1960s-1970s: The first electronic pocket calculators were developed, revolutionizing portable computing.
- 1980s-1990s: Scientific calculators became widely available for students and professionals.
- 21st Century: Online calculators like ours make advanced mathematical functions accessible to anyone with an internet connection.
