The image you uploaded is the cover of a game titled
"Subtraction With Regrouping Game." It appears to be an educational resource designed to help students practice subtraction problems that require regrouping (also known as borrowing). Below, I will explain what "subtraction with regrouping" means and provide an example to illustrate the concept.

What is Subtraction with Regrouping?
Subtraction with regrouping is a method used when subtracting numbers where the digit in the minuend (the number being subtracted from) is smaller than the corresponding digit in the subtrahend (the number being subtracted). In such cases, we need to "borrow" from the next higher place value to make the subtraction possible.
####
Steps for Subtraction with Regrouping:
1.
Align the numbers by place value.
2.
Start subtracting from the rightmost digit.
3.
If the top digit is smaller than the bottom digit, borrow from the next place value to the left.
4.
Decrease the borrowed place value by 1 and increase the current place value by 10.
5.
Continue this process until all digits are subtracted.

Example Problem:
Let’s solve a subtraction problem with regrouping step by step:
Problem:
\[ 52 - 37 \]
####
Step-by-Step Solution:
1.
Align the numbers:
\[
\begin{array}{c@{}c@{}c}
& 5 & 2 \\
- & 3 & 7 \\
\end{array}
\]
2.
Subtract the ones place:
- The ones digit in the minuend is 2, and the ones digit in the subtrahend is 7.
- Since \(2 < 7\), we need to borrow from the tens place.
- Borrow 1 from the tens place (5 becomes 4), and add 10 to the ones place (2 becomes 12).
- Now, subtract: \(12 - 7 = 5\).
3.
Subtract the tens place:
- After borrowing, the tens digit in the minuend is 4, and the tens digit in the subtrahend is 3.
- Subtract: \(4 - 3 = 1\).
4.
Combine the results:
- The final answer is \(15\).
\[
\begin{array}{c@{}c@{}c}
& \cancel{5}^4 & \overset{12}{2} \\
- & 3 & 7 \\
\hline
& 1 & 5 \\
\end{array}
\]
