Also, you might have seen that trick about how to remember the multiples of 9 before....
One time I wondered what would it do if I just continued the list past 90.
The first column counts up, the second column counts down. Whenever you reach zero in the second column, repeat the number in the first column.
0 9
1 8
2 7
3 6
4 5
5 4
6 3
7 2
8 1
9 0
9 9
10 8
11 7
12 6
13 5
14 4
15 3
16 2
17 1
18 0
18 9
19 8
20 7
21 6
22 5
23 4
...
Let's fast forward to " 909 "
...
90 9
91 8
92 7
93 6
94 5
95 4
96 3
97 2
98 1
99 0
99 9
100 8
101 7
102 6
103 5
