Solve Vertical Subtraction: 24 minus 5 Step-by-Step

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

• Step 1: Align the numbers vertically by place value, with larger on top.
• Step 2: Subtract the digit in the ones place.
• Step 3: Consider if regrouping is needed for subtraction.

Now, let's work through each step:

Step 1: Align the numbers vertically like this:
$\begin{array}{r} 24 \\ - \phantom{0}\\ ~~5 \\ \end{array}$

Step 2: Start subtraction at the units (ones) place and go from right (ones column) to left (tens column):

Subtract the ones place:
4 (top number) - 5 (bottom number) is not possible without borrowing because 4 is less than 5.

Step 3: Regroup: Borrow 1 ten from the tens place of the top number $24$:
- Turn the 2 tens into 1 ten, so it becomes 1 in the tens place, and add 10 to the ones place, turning it into 14.

Now we have:
$\begin{array}{r} 1 {14} \\ - \phantom{0}\\ ~~~5 \\ \end{array}$

Now subtract the ones: $14 - 5 = 9$
Subtract the tens: $1 - 0 = 1$ (as there are no tens in $5$).
Combine them to get 19.

Therefore, the solution to the problem is $19$.
