Thanks for asking.

I don't think they're actually 'simpler' in a 'visual' sense. It's more of how we say out the numbers. So, for example, we call 11 'eleven'. But in Chinese, we call it - literal translation - 'ten one'.

So, Gladwell thinks this made learning maths in Chinese easier, because of the language. You can check this article out for more detail: https://gineersnow.com/students/best-explanation-asians-good-math

Or Gladwell's book.

I honestly don't think this made things simpler. Nor does it contribute to the topic in question.
