What 𝑚 means
Its italic form signals math notation; the formula supplies the value. Italic type separates variables from prose and upright units: italic m can mean mass, while upright m is the SI symbol for metres.
Diophantus used an accented Greek letter for an unknown around 250–275 CE; its identity is disputed. In 1637, Descartes's La Géométrie used a, b, c for knowns and x, y, z for unknowns.
