Typo for explanation?

[Perceptiveeagle]

"However, from 10m + 7, which is equal to 5 × 2m + 5 + 7, our number must be 2 (mod 5)." Is this a typo, because shouldn't it be \(5 \times 2m + 5 + 2 \) (mod 5)

(Correct me if I'm wrong)

@perceptiveeagle Yes, this is a typo. I've passed it on, thanks for noticing!
