To solve the problem, we need to find the missing addends in each equation so that the sum equals the given total. Let's go through each equation step by step.
1. \( 3 + \bigcirc = 8 \)
- We need to find a number that, when added to 3, gives 8.
- \( 8 - 3 = 5 \)
- So, the missing addend is \( 5 \).
2. \( 8 + \bigcirc = 10 \)
- We need to find a number that, when added to 8, gives 10.
- \( 10 - 8 = 2 \)
- So, the missing addend is \( 2 \).
3. \( \bigcirc + 2 = 9 \)
- We need to find a number that, when added to 2, gives 9.
- \( 9 - 2 = 7 \)
- So, the missing addend is \( 7 \).
4. \( \bigcirc + 3 = 6 \)
- We need to find a number that, when added to 3, gives 6.
- \( 6 - 3 = 3 \)
- So, the missing addend is \( 3 \).
5. \( 5 + \bigcirc = 6 \)
- We need to find a number that, when added to 5, gives 6.
- \( 6 - 5 = 1 \)
- So, the missing addend is \( 1 \).
6. \( 2 + \bigcirc = 4 \)
- We need to find a number that, when added to 2, gives 4.
- \( 4 - 2 = 2 \)
- So, the missing addend is \( 2 \).
7. \( 1 + \bigcirc = 8 \)
- We need to find a number that, when added to 1, gives 8.
- \( 8 - 1 = 7 \)
- So, the missing addend is \( 7 \).
8. \( 5 + \bigcirc = 9 \)
- We need to find a number that, when added to 5, gives 9.
- \( 9 - 5 = 4 \)
- So, the missing addend is \( 4 \).
9. \( \bigcirc + 2 = 10 \)
- We need to find a number that, when added to 2, gives 10.
- \( 10 - 2 = 8 \)
- So, the missing addend is \( 8 \).
10. \( \bigcirc + 4 = 4 \)
- We need to find a number that, when added to 4, gives 4.
- \( 4 - 4 = 0 \)
- So, the missing addend is \( 0 \).
11. \( 6 + \bigcirc = 7 \)
- We need to find a number that, when added to 6, gives 7.
- \( 7 - 6 = 1 \)
- So, the missing addend is \( 1 \).
12. \( 7 + \bigcirc = 8 \)
- We need to find a number that, when added to 7, gives 8.
- \( 8 - 7 = 1 \)
- So, the missing addend is \( 1 \).
Final Answer:
\[
\boxed{
\begin{array}{cc}
3 + 5 = 8 & 8 + 2 = 10 \\
7 + 2 = 9 & 3 + 3 = 6 \\
5 + 1 = 6 & 2 + 2 = 4 \\
1 + 7 = 8 & 5 + 4 = 9 \\
8 + 2 = 10 & 0 + 4 = 4 \\
6 + 1 = 7 & 7 + 1 = 8 \\
\end{array}
}
