20+30+2=52
51+41+30=86
18+32+15=65

52+86+65=203 now I don't know what its sign would be but that is what it would equal all together without the signs

hope that helps

If I remember right, each column can only go up to 60. so add up to seconds, anything over 60 stays and 1 carries over to the minutes. add those up, anything over 60 stays, and 1 carries over to degrees. then add those.

I got 53° 27' 5"

Hello!

Find the coordinate where x = -1:

At x = -1, y = 1, so the coordinate is (-1, 1).

Find the coordinate where x = 2:

At x = 2, y = -2, so the coordinate is (2, -2).
