a number r is more than 0 or less than or equal to -8

r > 0 or r ≤ -8

Correct

To determine whether a number, r, is more than 0 or less than or equal to -8, you can use the following steps:

1. Start with the given number, r.
2. Check if r is more than 0.
3. If r is more than 0, it satisfies the condition of being "more than 0."
4. If r is not more than 0, check if it is less than or equal to -8.
5. If r is less than or equal to -8, it satisfies the condition of being "less than or equal to -8."
6. If r satisfies either condition (more than 0 or less than or equal to -8), you can conclude that the statement is true for that number.
7. If r does not satisfy either condition, then the statement is false for that number.

To determine if a number "r" is more than 0 or less than or equal to -8, you can follow these steps:

1. Compare the number "r" with 0: If "r" is greater than 0, then it satisfies the first condition of being "more than 0."

2. If "r" is not greater than 0, compare it with -8: If "r" is less than or equal to -8, then it satisfies the second condition of being "less than or equal to -8."

By applying these steps, you can determine if "r" meets the given conditions.
