To solve these problems, we need to find out what number added to 10 makes the total on the right side. Since all the numbers start with 10, we can just look at the ones place (the last digit) of the total to find the answer.
Here is the step-by-step solution for each problem:
1.
$10 + \_\_ = 16$
Think: 10 plus what equals 16? Since $16 - 10 = 6$, the answer is
6.
2.
$10 + \_\_ = 15$
Think: 10 plus what equals 15? Since $15 - 10 = 5$, the answer is
5.
3.
$10 + \_\_ = 13$
Think: 10 plus what equals 13? Since $13 - 10 = 3$, the answer is
3.
4.
$10 + \_\_ = 18$
Think: 10 plus what equals 18? Since $18 - 10 = 8$, the answer is
8.
5.
$10 + \_\_ = 10$
Think: 10 plus what equals 10? If you add nothing (zero), it stays 10. The answer is
0.
6.
$10 + \_\_ = 12$
Think: 10 plus what equals 12? Since $12 - 10 = 2$, the answer is
2.
7.
$10 + \_\_ = 17$
Think: 10 plus what equals 17? Since $17 - 10 = 7$, the answer is
7.
8.
$10 + \_\_ = 14$
Think: 10 plus what equals 14? Since $14 - 10 = 4$, the answer is
4.
9.
$10 + \_\_ = 11$
Think: 10 plus what equals 11? Since $11 - 10 = 1$, the answer is
1.
10.
$10 + \_\_ = 19$
Think: 10 plus what equals 19? Since $19 - 10 = 9$, the answer is
9.
11.
$10 + \_\_ = 19$
This is the same as number 10. The answer is
9.
12.
$10 + \_\_ = 19$
This is also the same as number 10. The answer is
9.
Final Answer:
1. 6
2. 5
3. 3
4. 8
5. 0
6. 2
7. 7
8. 4
9. 1
10. 9
11. 9
12. 9
