I think the word you're looking for is "basic arithmetic literacy". This should be obvious by the fact that it turns out the 100 million figure is for worldwide visits to stores, and only something like 40% of Walmart stores are even in the US. For those of us who aren't hobbled by a desperate need to be offended, little arithmetic spot-checks like the GP comment's are actually useful (in this case, revealing that his assumption of US-only visitors was flawed).

If one were looking for that, the word would be "numeracy".

I'm aware of the word numeracy, but writing is more art than science and "arithmetic numeracy" didn't strike the ear well (and leaving out the arithmetic qualifier would de-emphasize just how basic a numeracy I was referring to).

If all you can contribute to the conversation is pretending that stylistic choices are errors, it's probably better to contribute nothing at all.

That's fairly rich, considering that this entire thread is you telling me which words I ought to be "looking for". Fine, you win. The rest of the nation is just like you: those weeks we don't shop at "Hole Foods", we instead shop at "Trader Jo's". What's this "Wal-Mart"?
