Key Facts

  1. 1

    Al-Khwarizmi (820 AD): "father of algebra"; wrote Al-Kitab al-mukhtasar โ€” first systematic algebra book

  2. 2

    Linear equation: ax + b = 0; slope-intercept form: y = mx + c; simultaneous equations: two equations, two unknowns

  3. 3

    Applications: economics (supply/demand lines), science (rate of change), engineering (circuit analysis)

๐Ÿ”ข Did you know? "Algebra" comes from the Arabic "al-jabr" (reunion of broken parts) from al-Khwarizmi's 820 AD book โ€” his name also gave us "algorithm"
