Solve Decimal Addition: 30.07 + 6.06 Step-by-Step

To solve this problem, we will follow these steps:

• Step 1: Align the decimal numbers vertically.
• Step 2: Ensure the decimal points line up correctly.
• Step 3: Add the numbers starting from the hundredths place, then the tenths, whole numbers, carrying over any extra values if necessary.

Now, let's work through each step:

Step 1: Align the numbers vertically:

$\begin{array}{c} \phantom{+}30.07 \\ + \phantom{00}6.06 \\ \hline \end{array}$

Step 2: Add the numbers starting from the rightmost place (hundredths position):

• Hundredths: $7 + 6 = 13$, place 3 and carry over 1.
• Tenths: $0 + 0 + 1 = 1$.

Next, move to the whole numbers:

• Units: $0 + 6 = 6$.
• Then, tens: $3 + 0 = 3$.

The final sum is:

$\begin{array}{c} \phantom{+}30.07 \\ + \phantom{00}6.06 \\ \hline \phantom{+}36.13 \\ \end{array}$

Therefore, the solution to the problem is $36.13$.
