It looks like you've uploaded a photo containing some mathematical expressions. I will transcribe and solve them for you. The image contains the following expressions:

1. $9 \div 3$
2. $7 \times 7$
3. $14 + 3$
4. $33 - 7$
5. $12 \times 3 + 2$
6. $10 + 5$

Let's solve each of these:

1. $9 \div 3 = 3$
2. $7 \times 7 = 49$
3. $14 + 3 = 17$
4. $33 - 7 = 26$
5. $12 \times 3 + 2 = 36 + 2 = 38$
6. $10 + 5 = 15$

Here are the solutions:

1. $9 \div 3 = 3$
2. $7 \times 7 = 49$
3. $14 + 3 = 17$
4. $33 - 7 = 26$
5. $12 \times 3 + 2 = 38$
6. $10 + 5 = 15$
