Solve Vertical Subtraction: Finding the Difference Between 39 and 6

$\begin{aligned} &39 \\ -& \\ &~~6 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll follow these steps:

• Step 1: Write the numbers vertically, with each digit aligned in their respective place value.

• Step 2: Begin subtracting starting from the rightmost column.

• Step 3: Move to the left, repeating the process for each subsequent column until finished.

Now, let's work through each step:
Step 1: Arrange the numbers vertically, aligning according to the decimal place.
39
- 6
-----
Step 2: Start subtracting from the right. Subtract the ones place: $9 - 6 = 3$.
39
- 6
-----
3
Step 3: Since there is no need to borrow, move to the tens place:
The tens place comprises '3' from '39', as there is no corresponding digit above '6' to subtract from: $3 - 0 = 3$.
39
- 6
-----
33


Therefore, the solution to the problem is $33$.
