10k? 100k? A million?
I am not talking about calculating with numbers, but rather the point where numbers stop being comprehensible, or “no longer mean anything”.
Try visualizing exactly 10000 apples in your mind.
Edit: What I’ve gathered so far from the answers:
Visualizing: <10
7 sounds about right. When I see a number of stuff in front of me I can quickly grasp how many there are up to about 7. 8 already becomes two fours. 9 is 3x3 or 4+5 depending on how the objects are clustered.
Though I think I can estimate up to about a thousand. Usually by comparing to stuff I have already seen in that ballpark.
