I have successfully loaded the image. It contains a set of arithmetic problems involving addition, subtraction, multiplication, and division with positive and negative numbers. Let's solve each one step by step:

1. $(-18) \div (+6) = -3$
2. $(+6) - (+8) = -2$
3. $(+7) - (+9) = -2$
4. $(-15) \div (+3) = -5$
5. $(-3) \times (+3) = -9$
6. $(+2) \times (+3) = 6$
7. $(-30) \div (-6) = +5$
8. $(-24) \div (-3) = +8$
9. $(-49) \div (-7) = +7$
10. $(-3) - (+5) = -8$
11. $(-32) \div (+4) = -8$
12. $(+5) - (+3) = +2$
13. $(+9) + (+8) = +17$
14. $(+4) + (-4) = 0$

Let me know if you'd like any further details on these calculations or additional assistance!

Here are some related questions to consider:

1. How do you multiply two negative numbers?
2. What happens when you subtract a negative number from another negative number?
3. Why is division by negative numbers important in solving equations?
4. Can you explain why subtracting a larger positive number from a smaller one results in a negative number?
5. How do we handle parentheses in arithmetic operations?

Tip: Always perform multiplication and division before addition and subtraction unless parentheses indicate otherwise.
