To solve these problems, we need to find the missing number that adds up to 8. Each diagram shows the number 8 at the top, which means the two numbers at the bottom must add together to equal 8.
Here is the step-by-step solution for each problem:
1.
8 and ? make 8: Since $8 + 0 = 8$, the missing number is
0.
2.
7 and ? make 8: Since $7 + 1 = 8$, the missing number is
1.
3.
6 and ? make 8: Since $6 + 2 = 8$, the missing number is
2.
4.
7 and ? make 8: Since $7 + 1 = 8$, the missing number is
1.
5.
6 and ? make 8: Since $6 + 2 = 8$, the missing number is
2.
6.
? and 5 make 8: Since $3 + 5 = 8$, the missing number is
3.
7.
? and 6 make 8: Since $2 + 6 = 8$, the missing number is
2.
8.
? and 5 make 8: Since $3 + 5 = 8$, the missing number is
3.
9.
? and 4 make 8: Since $4 + 4 = 8$, the missing number is
4.
10.
? and 3 make 8: Since $5 + 3 = 8$, the missing number is
5.
11.
4 and ? make 8: Since $4 + 4 = 8$, the missing number is
4.
12.
5 and ? make 8: Since $5 + 3 = 8$, the missing number is
3.
13.
3 and ? make 8: Since $3 + 5 = 8$, the missing number is
5.
14.
4 and ? make 8: Since $4 + 4 = 8$, the missing number is
4.
15.
3 and ? make 8: Since $3 + 5 = 8$, the missing number is
5.
16.
? and 6 make 8: Since $2 + 6 = 8$, the missing number is
2.
17.
? and 2 make 8: Since $6 + 2 = 8$, the missing number is
6.
18.
? and 6 make 8: Since $2 + 6 = 8$, the missing number is
2.
19.
? and 5 make 8: Since $3 + 5 = 8$, the missing number is
3.
20.
? and 3 make 8: Since $5 + 3 = 8$, the missing number is
5.
21.
4 and ? make 8: Since $4 + 4 = 8$, the missing number is
4.
22.
1 and ? make 8: Since $1 + 7 = 8$, the missing number is
7.
23.
2 and ? make 8: Since $2 + 6 = 8$, the missing number is
6.
24.
0 and ? make 8: Since $0 + 8 = 8$, the missing number is
8.
25.
1 and ? make 8: Since $1 + 7 = 8$, the missing number is
7.
