It seems you have provided a mathematics activity sheet from an 8th-grade class. Here are some of the tasks included:

### Calculations:
1. Perform arithmetic operations, including handling of parentheses and integers, such as:
   - \( 18 - (-5 - 2 - 3) \)
   - \( 30 - (6 - 1 + 7) \)
   - \( 4 + (-5 + 0 + 8 - 4) \)
   - \( 4 + (3 - 5) + (-2 - 6) \)

2. Sign of products:
   - Two positive numbers
   - Two negative numbers
   - One positive and one negative number

3. Perform multiplications and divisions with positive and negative numbers:
   - \( (+5) \cdot (+3) \)
   - \( (-8) \cdot (+4) \)
   - \( (-40) \div (-5) \)
   - \( 500 \div (-25) \)

4. Solve more complex expressions such as:
   - \( -14 + \frac{42}{3} \)
   - \( (-4) \cdot (-5) + 8 \cdot (+2) \)
   - \( 36 \div (-6) + 5 \cdot 4 \)

### Additional problems:
- Word problems involving a hummingbird's wing flaps or the number of laps completed in a race.
  
Would you like to solve specific problems from this sheet? I can walk through each step to help.

### Follow-up questions:
1. Do you need assistance with handling negative numbers in the expressions?
2. Would you like a step-by-step explanation of any of the operations?
3. How would you like to approach word problems, such as the lap completion question?
4. Do you want to explore the rules for multiplying and dividing positive and negative numbers?
5. Should I help with solving one of the division problems listed?

### Tip:
When handling complex expressions, always solve the operations inside parentheses first and follow the order of operations (PEMDAS/BODMAS).

The query submitted by the user involves solving various arithmetic and algebraic expressions, verifying solutions to equations, and answering word problems related to cycling and hummingbirds.
