This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89

This is the biggest difference with Arabic numerals, as one cannot mechanically put 1 and 2 together to form 3, or 2 and 3 together to form 5. The adjacent image presents the steps in adding 3748 to 289: Place the augend 3748 in the first row, and the addend 289 in the second. Calculate from LEFT to RIGHT, from the 2 of 289 first.
