How was Gauss so productive with 6 children?

Probably sexual division of labor.

That's 30 more fingers he could count with.

I'd hazard by not dealing with them until they'd been schooled enough to operate as computers and GI (general intelligence) assistants.

There's a spread of farmers, railroad and telegraph directors, high level practical infomation management skills in the children.

He wasn't as productive as he could have been. This seems like Chuck Norris and Jeff Dean territory after all.

no TV

I only have 5 kids, and I am also not nearly as productive as Gauss but to a certain degree, it feels to me like responsibility kind of tries to force me to be more effective.

Chutzpah.
