Error in Explanation
-
After solving the question, I read the explanation but found a typo that needs to be fixed
. According to the problem, it says "has digits each less than or equal to 5", but in the explanation, it says "Notice that since a, b, c, and d are all less than five", which should be "Notice that since a, b, c, and d are all less than or equal to five,". -
@responsibleraccoon Yep, nice catch! I'll pass it on
-
@audrey Thanks!
-
@responsibleraccoon no problem!

@audrey One more thing...
"Notice that since a, b, c, and d are all less than or equal to five, the sum of each column will be less than 10. Then we can look at the digits of 14762 and directly see which of a, b, c and d were added together to get it. "
Should be:
Notice that since a, b, c, and d are all less than or equal to five, the sum of each column will be less than or equal to 10. Then we can look at the digits of 14762 and directly see which of a, b, c and d were added together to get it.
