The task involves solving addition problems using the "Making 10" strategy. This strategy helps simplify addition by breaking numbers into parts that add up to 10, making calculations easier.
Step-by-Step Solution:
####
1. \( 7 + 4 \)
- Break down the numbers to make 10:
- Take 3 from 4 to make 7 become 10.
- Remaining part of 4 is \( 4 - 3 = 1 \).
- So, \( 7 + 4 = (7 + 3) + 1 = 10 + 1 = 11 \).
Answer:
\[
7 + 4 = 11
\]
\[
\boxed{10 + 1 = 11}
\]
####
2. \( 9 + 8 \)
- Break down the numbers to make 10:
- Take 1 from 8 to make 9 become 10.
- Remaining part of 8 is \( 8 - 1 = 7 \).
- So, \( 9 + 8 = (9 + 1) + 7 = 10 + 7 = 17 \).
Answer:
\[
9 + 8 = 17
\]
\[
\boxed{10 + 7 = 17}
\]
####
3. \( 8 + 8 \)
- Break down the numbers to make 10:
- Take 2 from one 8 to make the other 8 become 10.
- Remaining part of 8 is \( 8 - 2 = 6 \).
- So, \( 8 + 8 = (8 + 2) + 6 = 10 + 6 = 16 \).
Answer:
\[
8 + 8 = 16
\]
\[
\boxed{10 + 6 = 16}
\]
####
4. \( 5 + 7 \)
- Break down the numbers to make 10:
- Take 5 from 7 to make 5 become 10.
- Remaining part of 7 is \( 7 - 5 = 2 \).
- So, \( 5 + 7 = (5 + 5) + 2 = 10 + 2 = 12 \).
Answer:
\[
5 + 7 = 12
\]
\[
\boxed{10 + 2 = 12}
\]
####
5. \( 4 + 9 \)
- Break down the numbers to make 10:
- Take 6 from 9 to make 4 become 10.
- Remaining part of 9 is \( 9 - 6 = 3 \).
- So, \( 4 + 9 = (4 + 6) + 3 = 10 + 3 = 13 \).
Answer:
\[
4 + 9 = 13
\]
\[
\boxed{10 + 3 = 13}
\]
####
6. \( 7 + 8 \)
- Break down the numbers to make 10:
- Take 3 from 8 to make 7 become 10.
- Remaining part of 8 is \( 8 - 3 = 5 \).
- So, \( 7 + 8 = (7 + 3) + 5 = 10 + 5 = 15 \).
Answer:
\[
7 + 8 = 15
\]
\[
\boxed{10 + 5 = 15}
\]
####
7. \( 6 + 6 \)
- Break down the numbers to make 10:
- Take 4 from one 6 to make the other 6 become 10.
- Remaining part of 6 is \( 6 - 4 = 2 \).
- So, \( 6 + 6 = (6 + 4) + 2 = 10 + 2 = 12 \).
Answer:
\[
6 + 6 = 12
\]
\[
\boxed{10 + 2 = 12}
\]
####
8. \( 8 + 6 \)
- Break down the numbers to make 10:
- Take 2 from 6 to make 8 become 10.
- Remaining part of 6 is \( 6 - 2 = 4 \).
- So, \( 8 + 6 = (8 + 2) + 4 = 10 + 4 = 14 \).
Answer:
\[
8 + 6 = 14
\]
\[
\boxed{10 + 4 = 14}
\]
Final Answers:
\[
\boxed{
\begin{array}{ll}
7 + 4 = 11 & 9 + 8 = 17 \\
8 + 8 = 16 & 5 + 7 = 12 \\
4 + 9 = 13 & 7 + 8 = 15 \\
6 + 6 = 12 & 8 + 6 = 14 \\
\end{array}
}
