Dec 14, 2016

$3.097$

#### Explanation:

$5.9 - 2.803$

The above can be rewritten as:
$5.900 - 2.803$

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

Now the last bit of subtraction can be done.
$3.100 - 0.003 = \left(3100 - 3\right) \cdot {10}^{-} 3 = 3097 \cdot {10}^{-} 3 = 3.097$
