Question

Help i dont understand this.

Answer 1

1 * 1 = 1
11 * 11 = 121
111 * 111 = 12321
1111 * 1111 = 1234321
11111 * 11111 = 123454321
111111 * 111111 = 12345654321

the pattern is that with each '1' added, there is another consecutive number added. if there are 3 ones, it I'll go up to 3 and then back down to 1 (111*111=12321)
it is the same like that for every one.
