Summary
1494 CE woodcut from Luca Pacioli's modification of Bede's finger calculus in Summa de arithmetica, geometrica, proportioni et proportionalita. Unlike Bede's original method, Pacioli modified the order of the handshapes for greater symmetry. The handshapes for 1 and 10 on the left hand therefore correspond to the 100s and 1000s on the right.
