The hyphen and negative sign in nemeth is the same.  How does the reader determine which sign is being used.

For example (problem taken from the online NFB  provisional lesson 2):  Plants thrive in soil that measure from 5.5-7.0 on the pH scale.

Taken in context I would know it was a hyphen, but other examples may not be as clear.

Thanks for your insight 🙂
