Ranges

We recommend writing ranges as follows:

(-1500; -950) or [-1500; -950] is more of a mathematical notation. Writing from -1550 to -950 or between -1550 and -950 or separating with en dash would be more common. However, in this case the en dash (`-1550 – -950') would be hard to read because of the negative sign. See some more details here: https://www.dailywritingtips.com/how-to-write-about-ranges/
