Spot on.

 

The numbers on every compass or HSI (or at least nearly all of them) have the numbers divided by 10. So 21 on the compass means 210°, 3 = 30° and so on.

For a question of design space sometimes the numbers on a magnetic's compas are shorter.But to offer the ability to recognize your position there are the four cardinals points pointed as : N , E ,S ,W.
NORTH, EAST, SOUTH, WEST.
Thus when you see a number like 24 and this is close to W(for WEST),you know that is 240°.
Same if the number 6 is close to E(for EAST),you know that is 60°.
You have to keep in mind one of these pics,and think you are in the center.

To help you have the gyroscopic compas.

Once you know what is the direction you go,you will know in which direction you have to turn.

I hope it's help a bit.

Just to add you should never use that short number in comms. "Heading 21" will always mean heading 021 or 21 degrees, never 210. HSI greatly helps in SA. Wherever your nose is pointing you just find the new direction on the wheel around your aircraft and see if it's on the left or the right side - now you know which way to turn.

There are step-by-step to use a compass that can useful for someone. Open the compass: Let the cover and the base form a 90-degree angle. Move the lens holder: Slightly push forward the lens holder. Hand placement: Insert your thumb through the thumb loop and the index finger along the compass. Place the three remaining fingers below as if you are holding a gun. On the other hand, wrap the fingers around the three fingers below the compass. Sight: Now peek through the rear sight slot, aligning the sighting wire or the front sight to the desired direction or object. Your cheek should be resting on the base of your thumb. Read the azimuth: Lastly, ensuring the dial is floating, look down on it and read the azimuth.
