This man is a child development expert who knows incontrovertible child development facts, like that children under twelve can't understand negative numbers.
My eight year old is going to find this hilarious when she wakes up.
The OP was saying I'm wrong about kids not understanding negative numbers until a certain age.
I know it's 12 and I know it's easy to look up. He didn't.
So I gave him another example of something that develops later, and you looked up the age as if it disproves my point.

I don't have a SoundCloud but my daughter attends oaklandlearn.org/ and receives math tutoring (over zoom!) from teegardentutoring.org/#/ and I couldn't possibly say enough good things about either.
