Solve Vertical Subtraction: 64 Minus 1 Step-by-Step

$\begin{aligned} &64 \\ -& \\ &~~1 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve the problem, let's perform the subtraction using the vertical method:

Step-by-Step Solution:
Given the problem:
$\begin{array}{c} 64 \\ - \, 1 \\ \hline \end{array}$

• Step 1: Align the numbers vertically with 64 on top and 1 on the bottom, making sure to align by the units place.
• Step 2: Subtract the digit 1 from the digit 4 in the units column:
$4 - 1 = 3$
• Step 3: Since there is no subtraction needed in the tens place (as 6 is only being carried over), bring down the 6:
$63$

Therefore, the result of the subtraction $64 - 1$ is $\boxed{63}$.

Since the correct answer matches the choices given, the correct multiple-choice answer is Choice 2.
