Why are the n, s, e, and w designations often omitted from coordinates on u. s. topographic maps?

In a Topographic map,  here are the programming values of each of that navgations:

N = positive value to the latitude
S= Negative value to the Latitude
W = Positive value to the longitude
E = Negative value to the longitude

Most programmers that work to create the topographic map choose to simply ommit the N,S,W,&E because it will save them a lot of time from having to type in a minus sign before most of their longitude values in code writing.

The answer is ocho because ocho is 8
