I have this DEM file downloaded from the internet. It's a text-formatted file and it looks like this:

1440   720    30 -9999   450
-9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999
-9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999  -9999
...

and so on...

How do I open it in ArcMap to see it visually? Or should I open it with another software?

Based on Michael Stimson's answer, I've changed the header of the file into

ncols        1440
nrows        720
xllcorner    30
yllcorner    450
cellsize     1.000000000000
NODATA_value  -9999  

It worked like a charm afterwards
