One solution:
0990 + 0000 + 0000 + 0066 + 0055 = 1111
21
This is impossible. 21 is an odd number and all these digits are odd. Whenever you add 6 odd numbers together, the answer is always even!
There are 18 111, 222, 333, 444, 555, 666, 777, 888, 999, 1111, 2222, 3333, 4444, 5555, 6666, 7777. 8888. 9999

Oh, what a lovely question! You can create 6 combinations by repeating the same number 4 times. It's like painting a beautiful pattern with numbers - 1111, 2222, 3333, 4444, 5555, and 6666. Each combination is unique and special in its own way, just like every brushstroke on a canvas.
0.5555 = 5555/10000 = 1111/2000
9915 1159 5555 9999 1111
5+5+5+1+1+4=21
1, 5, 11, 55, 101, 505, 1111, 5555.
The factors of 5555 are 1, 5, 11, 55, 101, 505, 1111, and 5555. The prime factors of 5555 are 5, 11, and 101.

2222= 3 mod 7 5555 = 4 mod 7 2222^5555 + 5555^2222 = (3^5)^1111 + (4^2)^ 1111 as it is a^n + b^n and n is odd so it is divisible by (a+b) 3^5 + 4^ 2 = 259 hence by 7 as 7 is a factor of 259
0.05555 = 5555/100000 = 1111/20000
