3.097

Explanation:

5.9 - 2.803

The above can be rewritten as:
5.900 - 2.803

Then in steps the numbers can be subtracted.
5-2 = 3
0.9 - 0.8 = 0.1
0.00 - 0.00 = 0.00
0.000 - 0.003 = -0.003
3 + 0.1 + 0.00 + (-0.003) = 3.100 - 0.003

Now the last bit of subtraction can be done.
3.100 - 0.003 = (3100 - 3)*10^-3 = 3097*10^-3 = 3.097
