To solve the problem of finding the missing numbers, we will use the concept of inverses. This means we will reverse the operations (addition or subtraction) to find the unknowns. Let's solve each equation step by step.
First Row:
1.
Equation 1:
\[
4 \square + 15 = 56
\]
To find the missing number, subtract 15 from 56:
\[
56 - 15 = 41
\]
So, the missing number is \(1\).
2.
Equation 2:
\[
\square 5 - 43 = 52
\]
To find the missing number, add 43 to 52:
\[
52 + 43 = 95
\]
So, the missing number is \(9\).
3.
Equation 3:
\[
25 + 1\square = 39
\]
To find the missing number, subtract 25 from 39:
\[
39 - 25 = 14
\]
So, the missing number is \(4\).
Second Row:
4.
Equation 4:
\[
22 + \square 5 = 57
\]
To find the missing number, subtract 22 from 57:
\[
57 - 22 = 35
\]
So, the missing number is \(3\).
5.
Equation 5:
\[
2\square - 12 = 15
\]
To find the missing number, add 12 to 15:
\[
15 + 12 = 27
\]
So, the missing number is \(7\).
6.
Equation 6:
\[
7\square - 43 = 32
\]
To find the missing number, add 43 to 32:
\[
32 + 43 = 75
\]
So, the missing number is \(5\).
Third Row:
7.
Equation 7:
\[
\square 1 - 41 = 10
\]
To find the missing number, add 41 to 10:
\[
10 + 41 = 51
\]
So, the missing number is \(5\).
8.
Equation 8:
\[
\square 9 - 59 = 00
\]
To find the missing number, add 59 to 00:
\[
00 + 59 = 59
\]
So, the missing number is \(5\).
9.
Equation 9:
\[
21 + 4\square = 65
\]
To find the missing number, subtract 21 from 65:
\[
65 - 21 = 44
\]
So, the missing number is \(4\).
Final Answer:
\[
\boxed{1, 9, 4, 3, 7, 5, 5, 5, 4}
\]
