Solve Vertical Addition: 862 + 4 Step-by-Step

To solve the problem of adding $862$ and $4$ vertically, follow these steps:

• Step 1: Align the numbers as follows:
  $\begin{array}{c} 862 \\ + 4 \\ \underline{\phantom{776}} \\ \end{array}$
• Step 2: Add the digit in the units’ place:
  $2 + 4 = 6$
• Step 3: Since $6$ is less than $10$, place the $6$ directly in the units’ place of the result:
