Studdy Solution

STEP 1

1. We are solving the subtraction problem $25 - 8$ .
2. The problem requires regrouping (borrowing) because the ones digit in 25 is smaller than the ones digit in 8.

STEP 2

1. Set up the subtraction problem.
2. Regroup (borrow) to make subtraction possible.
3. Perform the subtraction.

STEP 3

Write the subtraction problem vertically, aligning the digits by place value:
$\begin{array}{c} 25 \\ - 8 \\ \hline \end{array}$

STEP 4

Since the ones digit in 25 (which is 5) is smaller than the ones digit in 8, we need to regroup.

STEP 5

Regroup by borrowing 1 ten from the tens place in 25, changing the tens digit from 2 to 1, and adding 10 to the ones digit, changing it from 5 to 15.
$\begin{array}{c} 1\cancel{2}5 \\ - 8 \\ \hline \end{array}$
Becomes:
$\begin{array}{c} 1\ 15 \\ - 8 \\ \hline \end{array}$

STEP 6

Subtract the ones digits: $15 - 8 = 7$ .
$\begin{array}{c} 1\ 15 \\ - 8 \\ \hline 7 \\ \end{array}$

STEP 7

Subtract the tens digits: $1 - 0 = 1$ .
$\begin{array}{c} 1\ 15 \\ - 8 \\ \hline 17 \\ \end{array}$
The result of the subtraction $25 - 8$ is:
$\boxed{17}$
