The task involves solving addition problems using dominoes. Each domino has two sections, and the number of dots in each section represents a number. The goal is to add the numbers on the left and right sides of each domino and write the sum in the circle provided.
Step-by-Step Solution:
1.
First Row:
-
Domino 1:
- Left side: 2 dots
- Right side: 3 dots
- Sum: \( 2 + 3 = 5 \)
-
Domino 2:
- Left side: 6 dots
- Right side: 5 dots
- Sum: \( 6 + 5 = 11 \)
2.
Second Row:
-
Domino 3:
- Left side: 4 dots
- Right side: 6 dots
- Sum: \( 4 + 6 = 10 \)
-
Domino 4:
- Left side: 2 dots
- Right side: 1 dot
- Sum: \( 2 + 1 = 3 \)
3.
Third Row:
-
Domino 5:
- Left side: 1 dot
- Right side: 1 dot
- Sum: \( 1 + 1 = 2 \)
-
Domino 6:
- Left side: 5 dots
- Right side: 7 dots
- Sum: \( 5 + 7 = 12 \)
4.
Fourth Row:
-
Domino 7:
- Left side: 3 dots
- Right side: 2 dots
- Sum: \( 3 + 2 = 5 \)
-
Domino 8:
- Left side: 6 dots
- Right side: 6 dots
- Sum: \( 6 + 6 = 12 \)
5.
Fifth Row:
-
Domino 9:
- Left side: 5 dots
- Right side: 5 dots
- Sum: \( 5 + 5 = 10 \)
-
Domino 10:
- Left side: 4 dots
- Right side: 4 dots
- Sum: \( 4 + 4 = 8 \)
6.
Sixth Row:
-
Domino 11:
- Left side: 8 dots
- Right side: 8 dots
- Sum: \( 8 + 8 = 16 \)
-
Domino 12:
- Left side: 1 dot
- Right side: 1 dot
- Sum: \( 1 + 1 = 2 \)
7.
Seventh Row:
-
Domino 13:
- Left side: 4 dots
- Right side: 4 dots
- Sum: \( 4 + 4 = 8 \)
-
Domino 14:
- Left side: 2 dots
- Right side: 2 dots
- Sum: \( 2 + 2 = 4 \)
Final Answers:
\[
\begin{array}{|c|c|}
\hline
\text{Domino} & \text{Sum} \\
\hline
2 + 3 & 5 \\
6 + 5 & 11 \\
4 + 6 & 10 \\
2 + 1 & 3 \\
1 + 1 & 2 \\
5 + 7 & 12 \\
3 + 2 & 5 \\
6 + 6 & 12 \\
5 + 5 & 10 \\
4 + 4 & 8 \\
8 + 8 & 16 \\
1 + 1 & 2 \\
4 + 4 & 8 \\
2 + 2 & 4 \\
\hline
\end{array}
\]
Thus, the final answers are:
\[
\boxed{5, 11, 10, 3, 2, 12, 5, 12, 10, 8, 16, 2, 8, 4}
\]
