Solve Vertical Addition: Finding the Sum of 178 + 12

Question

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

00:00 Solve

00:03 Each time we calculate the sum of 2 digits, and then we place

00:06 Let's start by adding ones with ones

00:09 Place the ones, and add 1 to the tens

00:15 Add tens with tens, remember to add 1 to the calculation

00:19 Place in the tens position

00:24 Place 0 in the missing digits

00:27 Add hundreds with hundreds, place in hundreds position

00:30 And this is the solution to the question

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: $190$ .
