Question

How do you simplify `5.9-2.803`?

Answer 1

`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`
