Find the value of the following :
12 + 18 = _________________

Answer

To find the value of \( 12 + 18 \), we will follow these steps:

### Step 1: Write down the numbers to be added.
We have:
\[ 12 + 18 \]

### Step 2: Add the units place.
Look at the units digit of both numbers:
- The units digit of 12 is 2.
- The units digit of 18 is 8.

Now, add these two:
\[ 2 + 8 = 10 \]
Since 10 is greater than 9, we write down 0 and carry over 1 to the next column.

### Step 3: Add the tens place.
Next, look at the tens digit of both numbers:
- The tens digit of 12 is 1.
- The tens digit of 18 is 1.

Now, add these two along with the carry from the previous step:
\[ 1 + 1 + 1 = 3 \]

### Step 4: Combine the results.
Now, we combine the results from the units and tens place:
- The tens place gives us 3.
- The units place gives us 0.

Thus, the final answer is:
\[ 30 \]

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