What if 2 of the 3 digits are the same?
If 2 digits are the same : -
223 334 566
322 343 656
+232 +433 +665
777 ÷ 7=111 1110 ÷ 10=111 1887 ÷ 17=111
224 559 772
242 595 727
+422 +955 +277
888 ÷ 8=111 2109 ÷19=111 1776 ÷ 16=111
It seems that when 2 of the 3 digits are the same the answer to the problem is 111.
Can I use Algebra to explain this?
aab=100a+10a+b
aba=100a+10b+a
+baa=100b+10a+a
222a+111b = 111(2a+b)
2a+b
=111
What if all 3 digits are the same number?
If All Digits Are The Same : -
333 = 37 444 = 37 666 = 37 999 = 37 777 _ = 37
9 12 18 27 21
It seems that when all the 3 digits are the same number the answer to the problem is 37.

What if I used 4 digits instead 3 digits to investigate the answer to the problem?
If All 4 Digits Are Different : -

4132 _ 5243 _ 5123
+ 4123 = 66660 ÷ 10=6666 +5234 = 93324 ÷ 15=6666| +5132 = 73326 ÷ 11=6666
It seems that for 4 digits, when all digits are different the answer to the problem is 6666.

What if I do the same problem but with 5 digits instead of 4 or 3?
From the data I have gathered maybe I can guess the outcomes for 5 digits.
