+A googol (10^100) is a massive number: one followed by one-hundred zeros;
+100^100 is almost unimaginably large: one followed by two-hundred zeros.
+Despite their size, the sum of the digits in each number is only 1.
+
+Considering natural numbers of the form, ab, where a, b < 100,
+what is the maximum digital sum?
