Question for math geeks! What do you call a....

Does anybody know what it is called when a system uses 0 to
specify the first occurence of something (instead of 1)? For example:

“Because UNIX is a <terminology_here> system, the first engine in the application is listed as “engine 0” in the output.”

I mean – I know we use it all the time, but what is this called???

Sign me totally puzzled.

How about “Because UNIX uses offsets instead of ordinals. . .”

I don’t know if this is what you’re looking for, but in programming, arrays that start with 0 rather than 1 are often just referred to as being ‘zero-based’.

Parabola!

Hypotenuse!

Ummm, L’Hospital’s Rule?

Differentiable?

oh, never mind.

You’re talking about the difference between integers “0…1…2…3” and counting numbers “1…2…3…4”

This is what my 7th grade algebra teacher taught.
