Answer

To solve the question "On subtracting -13 from -8, we get", we can follow these steps:

### Step 1: Understand the operation
We need to subtract -13 from -8. In mathematical terms, this can be written as:
\[ -8 - (-13) \]

### Step 2: Apply the rule of subtracting a negative number
Subtracting a negative number is the same as adding its positive counterpart. Therefore, we can rewrite the expression:
\[ -8 - (-13) = -8 + 13 \]

### Step 3: Perform the addition
Now we need to add -8 and 13. Since we are adding a negative number and a positive number, we can find the difference between their absolute values and then determine the sign:
\[ |13| - |8| = 13 - 8 = 5 \]
Since 13 is greater than 8, the result will be positive. Thus:
\[ -8 + 13 = 5 \]

### Final Answer
On subtracting -13 from -8, we get:
\[ \boxed{5} \]
