 8 #  Around the world, abaci have been used in pre-schools and elementary
 9 #
10 # In Western countries, a bead frame similar to the Russian abacus but
11 # with straight wires and a vertical frame has been common (see image).
12 # Helps schools as an aid in teaching the numeral system and arithmetic

14 #         |00000*****   |     row factor 1000000000
15 #         |00000*****   |     row factor 100000000
16 #         |00000*****   |     row factor 10000000 
17 #         |00000*****   |     row factor 1000000
18 #         |00000*****   |     row factor 100000
19 #         |00000*****   |     row factor 10000

27 # Each row represents a different row factor, starting with x1 at the
28 # bottom, ascending up to x1000000000 at the top row.
