> Ingvar Kamprad, founder of IKEA, had a hard time remembering numbers and numbers

And also numbers I assume. Does it mean something like “endless stream of numbers”?

I’m very surprised that they have 2000-3000 new products every year. Checking every name against every language of countries they operate in to avoid “bad” names must be a pain.

The Swedish version of the page just says "siffror" (literally "digits", but colloquially "numbers") once.

I'm not aware of any relevant Swedish expression that would repeat the same word like that. Maybe something like "siffror och tal", where both words could be translated as "numbers" by someone not paying attention to the resulting sentence. :)

A subdivision of people who know every obscenity in the world would be chuckleworthy, but I guess they use a validation program.

Seems like a mistake. No expression like that in Swedish at least.
