While you more than enough defend working memory and memorization capacity, I figured I'd chime in with additional supporting documentation. Cognitive load theory models short time memory as scarce and finite in nature. With each "number", you have less freely available working memory to use AND maintaining those values places their own stress. Current theories about long term memory (or "memorization capacity") consider it infinite in capacity.
