To perform the subtraction, let's align the numbers vertically:

  5
- 4
  ----

This results in 1.

Next, we have:

  11
- 5
 -----

Evaluating this gives us 6.

Combining everything, we have:

4
  1
-  6
 -----

Now, we perform the final formatting to give the answer clearly:

5 - 4 = 1
11 - 5 = 6

So, the results are:

1. The result of 5 - 4 is 1.
2. The result of 11 - 5 is 6.
