Solve the Decimal Subtraction: 4.1 - 0.1 Step by Step

To solve this problem, we'll perform the subtraction $4.1 - 0.1$.

Here are the steps we will follow:

• Step 1: Align the decimal points for both numbers.
• Step 2: Subtract each corresponding digit starting from the rightmost position.
• Step 3: Ensure the decimal point in the result is directly below the decimal points of the numbers being subtracted.

Now, let's work through each step:

Step 1: Align the numbers:
$\begin{array}{r} 4.1 \\ - 0.1 \\ \hline \end{array}$

Step 2: Perform the subtraction digit by digit:

The tenths column calculation:
$1 - 1 = 0$

The units column calculation:
$4 - 0 = 4$

Step 3: Write down the resulting number with the decimal point correctly placed:
$\begin{array}{r} 4.0 \\ \hline 4 \end{array}$

Since the trailing zero in $4.0$ is not necessary, we can write our final answer as $4$.

Therefore, the solution to the problem $4.1 - 0.1$ is $4$.
