See if you can solve this one. 8809=6 5555=0 7111=0 8193=3 2172=0 8096=5 6666=4 1012=1 1111=0 7777=0 3213=0 9999=4 7662=2 7756=1 9313=1 6855=3 0000=4 9881=5 2222=0 5531=0 3333=0 2581=????
The question is, King, did you deduce that logically by figuring out a pattern that fits every number on there and then applying it to 2581, like I did? Or did you guess something that seemed right?
Spoiler 2 *Claps for those figuring it out without using this or google* ^^ Truth be told there are two ways to solve this problem. And a kindergartener might figure out this faster than a math professor.
2 ways? I feel like I went the kindergartener route... <_< This reminds me of the "cosmic numbers" riddle, though.
Ah God.. after examining the millionth crazy insert-random-operators-at-random-places idea, I just saw the "pattern". I might have continued for hours.
