Solve Vertical Addition: 24 + 4 Step-by-Step

$\begin{aligned} &24 \\ +& \\ &~~4 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll add the numbers 24 and 4 using vertical addition:

• Step 1: Align the numbers vertically with the units and tens digits properly aligned:
$\begin{aligned} &24 \\ +& \\ &~~4 \\ \end{aligned}$

• Step 2: Add from the rightmost column (units position):
  The units digits are 4 and 4. Their sum is $4 + 4 = 8$.
• Step 3: Move to the next column (tens position):
  In this case, the tens digit of the first number is 2, and there is no tens digit in the number 4. Since there is no carry, we simply bring down the 2.

The sum of the numbers is 28, which is represented as:

$\begin{aligned} &28 \end{aligned}$

Therefore, the correct answer is 28, which corresponds to choice .
