Sorry, it is correct. 4010 is split to 40⋅10² + 10, and
3020 is split to 30⋅10² + 20. 40⋅10² ⋅ 30⋅10² = 40⋅30⋅10⁴.
Simplifying further to 4⋅3⋅10⁶ would be misleading as that
is not how it is calculated in the Karatsuba algorithm,
rather 40⋅30 is calculated with Karatsuba algorithm and
therefore split again.
