For discussing with better notations, the numbers one, two, three, ...., to one hundred will be denoted by:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
11, 12, 13, 14, 15, 16, 17, 18, 19, 20
21, 22, 23, 24, 25, 26, 27, 28, 29, 30
31, 32, 33, 34, 35, 36, 37, 38, 39, 40
41, 42, 43, 44, 45, 46, 47, 48, 49, 50
51, 52, 53, 54, 55, 56, 57, 58, 59, 60
61, 62, 63, 64, 65, 66, 67, 68, 69, 70
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
81, 82, 83, 84, 85, 86, 87, 88, 89, 90
91, 92, 93, 94, 95, 96, 97, 98, 99, 100
Afterward, since this is a world not so closed to the real world, we need not to care about our customs about counting. After 100, we might have, for example, 119, 120, 169, and even more: 696, 697, 985, 4059, 4060, 5741, 23660, 23661, 33461, .... , and so on. Note that these expressions are called decimal expressions about numbers.
