Where do math symbols come from? - John David Walters
TED-Ed・2 minutes read
Mathematician Robert Recorde introduced the equals sign in the 16th century to streamline algebraic expressions, while various other symbols, like the plus sign and exclamation mark, were created to simplify mathematical notation and improve communication efficiency. Mathematical symbols, often based on Latin or Greek alphabets, represent unknowns, relationships between variables, operations, and help condense complex calculations into concise expressions, enhancing clarity in mathematical communication.
Insights
- Mathematical symbols like the equals sign introduced by Robert Recorde in the 16th century aimed to streamline algebraic expressions by replacing wordy descriptions, making mathematical communication more efficient and concise.
- The adoption of various mathematical symbols, whether directly correlated to their meanings or more arbitrary, from Latin or Greek alphabets facilitated representing unknown quantities, operations, and relationships between variables, enhancing the clarity and effectiveness of mathematical expressions.
