Let’s solve each addition problem one by one. We’ll add the two numbers together and write the answer in the blank.
We’ll go in order from 1 to 20:
1) 3 + 2 = 5
2) 2 + 3 = 5
3) 1 + 4 = 5
4) 4 + 1 = 5
5) 5 + 2 = 7
6) 6 + 1 = 7
7) 0 + 3 = 3
8) 3 + 2 = 5
9) 5 + 1 = 6
10) 2 + 4 = 6
Now the second column:
11) 2 + 5 = 7
12) 5 + 3 = 8
13) 7 + 2 = 9
14) 1 + 7 = 8
15) 5 + 2 = 7
16) 4 + 4 = 8
17) 2 + 6 = 8
18) 1 + 9 = 10
19) 3 + 5 = 8
20) 8 + 2 = 10
Let me double-check a few to make sure I didn’t make a mistake:
- 3 + 2 is definitely 5
✔
- 5 + 2 is 7
✔
- 0 + 3 is just 3
✔
- 4 + 4 is 8
✔
- 8 + 2 is 10
✔
All look correct!
Final Answer:
1) 5
2) 5
3) 5
4) 5
5) 7
6) 7
7) 3
8) 5
9) 6
10) 6
11) 7
12) 8
13) 9
14) 8
15) 7
16) 8
17) 8
18) 10
19) 8
20) 10
