I disagree and stand by my answer.

To use your quotes

"The angle between Magnetic North and the direction indicated by a compass needle is called the angle of DEVIATION"

If you have a deviation of -2 degrees then you must add 2 degrees to your compass heading to get magnetic north.

To visualise this draw a line straight up and call this magnetic north.
now draw a line 2 degrees to the left of it (i.e. to the West as everyone is saying minus is to the West).

using your own quote
"Deviation is the angle between Magnetic North and Compass North measured in degrees East or West FROM Magnetic North"

Although my compass heading is now saying north It is actually pointing 2 degrees to the west of north.
Therefore I must add these 2 degrees on to my compass heading
to get true magnetic.

so 195 compass heading must have 2 degrees added to give true magnetic therefore 197 is the answer.

The answer is in your own quote "FROM Magnetic North"

Yours and everyone elses answers are going FROM COMPASS NORTH.

You are all saying that magnetic north is 2 degrees to the west of your compass North.

If you take the two degrees off you are then out by 4 degrees.
