where did the shape of numbers come from
Arabic numerals Arabic numerals, also called Hindu–Arabic numerals,[1][2] are the ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, based on the Hindu–Arabic numeral system,[3] the most common system for the symbolic representation of numbers in the world today. In this numeral system, a sequence of digits such as "975" is read as a single number, using the position of the digit in the sequence to interpret its value. They are descended from the Hindu-Arabic numeral system developed by ancient Indian mathematicians around 500 CE.[3]
Pi The Indian astronomer Aryabhata used a value of 3.1416 in his Āryabhaṭīya (499 AD).[58] Fibonacci in c. 1220 computed 3.1418 using a polygonal method, independent of Archimedes.[59] Italian author Dante apparently employed the value 3+√2/10 ≈ 3.14142.[59]
