Let's evaluate the expressions for each statement step by step:

1. A diver swims at 14 feet below sea level and then another 14 feet:
- Expression: [tex]\( 14 + (-14) \)[/tex]
- Calculating: [tex]\( 14 - 14 = 0 \)[/tex]
- Result: [tex]\( 0 \)[/tex], which simplifies to true.

2. Bailey owes [tex]$14 and then earns $[/tex]14:
- Expression: [tex]\( -14 + 14 \)[/tex]
- Calculating: [tex]\( -14 + 14 = 0 \)[/tex]
- Result: [tex]\( 0 \)[/tex], which simplifies to true.

3. Gail saves [tex]$14 and then spends $[/tex]14:
- Expression: [tex]\( -14 + 14 \)[/tex]
- Calculating: [tex]\( -14 + 14 = 0 \)[/tex]
- Result: [tex]\( 0 \)[/tex], which simplifies to true.

4. Max saves [tex]$14 and then spends $[/tex]14:
- Expression: [tex]\( 14 + (-14) \)[/tex]
- Calculating: [tex]\( 14 - 14 = 0 \)[/tex]
- Result: [tex]\( 0 \)[/tex], which simplifies to true.

5. Sera owes [tex]$14 and then earns $[/tex]14:
- Expression: [tex]\( -14 + 14 \)[/tex]
- Calculating: [tex]\( -14 + 14 = 0 \)[/tex]
- Result: [tex]\( 0 \)[/tex], which simplifies to true.

By evaluating all these expressions, each one of them results in true. Therefore, all the given statements are true.
