Evidence

Al-Khwarizmi also wrote On Indian Calculation (the Latin title was Algoritmi de numero indorum), which introduced readers of the Latin version to the use of what today we call ‘Arabic numerals’, though, as the title of the treatise indicates, such numerals actually originated in India. — Robert Irwin, For Lust of Knowing, 62
