Solve Decimal Addition: 13.4 + 4.5 + 0.1 Step by Step

To solve this problem, we'll follow these steps:

• Step 1: Align the decimal numbers by their decimal points: $13.4$, $4.5$, and $0.1$.

• Step 2: Perform the addition column by column, starting from the rightmost side.

• Step 3: Sum the values, taking care of decimal alignment.

Now, let's work through each step:

Step 1: Prepare the addition by aligning the decimal points:
13.4
+ 4.5
+ 0.1

Step 2: Start from the rightmost digits (tenths place):
$0.4 + 0.5 + 0.1 = 1.0$

Step 3: Now, add the whole number places:
$13 + 4 + 0 = 17$

Add these results together:
$17 (\text{whole number}) + 1.0 (\text{from tenths}) = 18.0$

Therefore, the solution to the problem is $18$.
