Solve Vertical Addition: Finding the Sum of 178 + 12

$\begin{aligned} &178 \\ +& \\ &~~12 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we will perform vertical addition:

• Step 1: Write the numbers vertically, aligning by place value. We have 178 on top and 12 below.
• Step 2: Start by adding the units column: $8 + 2 = 10$. Write 0 below the line and carry over 1 to the next column.
• Step 3: Move to the tens column. Add $7 + 1 = 8$ from 178 and the carry over 1, which equals $8 + 1 = 9$. Write 9 below the line.
• Step 4: Finally, add the hundreds column, where we have 1 with no carry over involved. Write 1 below the line.

After completing these steps, the vertical addition gives us the sum: $190$.
