Whose version of the number zero most closely resembles the number zero used in the US?

To find out whose version of the number zero most closely resembles the number zero used in the US, you can compare the different numeral systems. The number systems generally fall into two categories: Eastern Arabic numerals and Western Arabic numerals.

In the US, as well as in most Western countries, the Western Arabic numeral system is used. In this system, the number zero is represented by a circle or a small oval shape.

On the other hand, in the Eastern Arabic numeral system, which is commonly used in many Eastern countries, the number zero is represented by a dot or a small circle.

Considering these two options, the version of zero used in the US, with a circular or oval shape, most closely resembles the Western Arabic numeral system. Therefore, the number zero used in the US is most similar to the zero in countries that also use the Western Arabic numeral system, such as most Western countries including Canada, the UK, and Australia.
