Find the value of the following :
-12 - 18 = __________

Answer

To find the value of -12 - 18, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the numbers**: We have two negative integers: -12 and -18.

2. **Combine the negative integers**: When we subtract a positive number from a negative number, we can think of it as adding the absolute values of those numbers. Thus, we can rewrite the expression:
\[ -12 - 18 = -12 + (-18) \]

3. **Add the absolute values**: Now, we can add the absolute values of 12 and 18:
\[ 12 + 18 = 30 \]

4. **Apply the negative sign**: Since both numbers were negative, the result will also be negative:
\[ -12 - 18 = -30 \]

### Final Answer:
\[ -12 - 18 = -30 \]
