I can absolutely try this. Doesn't mean i'll solve it. If i solve it there's no guarantee i'll be correct. Math gets way harder when i don't have a legitimate need to do it. This falls in the "no legit need" so my mind went right to "100 * 70, good enough."

Or you could do (100 + 1)*70 => 100*70 + 1*70
I think therefore I am calculator?
Very easy to solve, just like it is easy to solve many other ones once you know the tricks.

Completely missing the point on purpose?
Elaborate.

Um, that's really easy to do in your head, there's no carrying or anything? 7,070
7 * 101 = 707 * 10 = 7,070
And computers don't brute-force multiplication either, so I'm not sure how this is relevant to the comment above?
I think it is very relevant, because no brute-forcing is involved in this solution.
That's not true, the 'brute force' part is searching for a shortcut that works.
