-1 OR 5*5=25 --

Here are the common interpretations. Tell me which one matches your context.

1. Boolean logic (nonzero = true)

• -1 is true (nonzero)
• 5*5 = 25 is true
• true OR true = true
• Result: true (often represented as 1)

2. If you mean bitwise/typical programming evaluation (e.g., C-style)

• 5*5 == 25 evaluates to 1 (true)
• -1 is treated as an integer (all bits 1)
• -1 | 1 (bitwise OR) = -1
• Result: -1

3. Pure arithmetic/boolean algebra (interpreting the whole thing as a boolean statement)

• Both sides are true; OR of true and true is true
• Result: true

If you can tell me the exact context (math, Python/Java/C/C++, logic exam, etc.), I can tailor the answer or show the exact syntax.
