Did you know that the number system in most common use today originated in the Arab world, hence the name Arabic numerals? You probably know this. However, you probably did not know that the numbers 1, 2, 3, 4 ...... up to 9 are not just some random figures representing values. Instead, these figures were purposefully designed by their inventor to enable readers to decipher the value of a number by following just one rule; the value of a number is equivalent to the number of angles in the figure. Below is what the numbers 1 to 9 looked like at their inception.The blue dots mark the angles.

Following this logic, you can easily deduce how Zero (0) was arrived at. Ingenious!

Very true
I remember reading this and much, much more, years ago in history of mathematics at college

I believe this is why guys like @Introvert don't mind the blood, sweat and money used on project cars.

Didn't they copy it from ancient India?

Didn't they copy it from ancient India?

Arabic borrowed and still uses Indian numerals while Europe borrowed Arabic numerals. By the time Arabic numerals were being invented, Indian numerals had already been introduced in the region. The new Arabic numerals did not render too well in Arabic calligraphy. Actually, they caused confusion when writers rounded the corners from habit and the natural tendency to avoid pen stops. Therefore, the Indian numerals stuck since they had already established themselves.
