## Description
|
|
<section id='description'>
|
|
A googol (10100) is a massive number: one followed by one-hundred zeros; 100100 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?
