-1 OR 5*5=26 --

I’m not sure of the exact context. Here are a few common interpretations. Tell me which matches your exam style, or share more details.

1. Logical OR in C/Java-style languages

• Expression: (-1) || (5*5 == 26)
• 5*5 == 26 is false (25 != 26)
• -1 is nonzero, so true
• true || false evaluates to true
• Result: 1 (true)

2. Logical OR in Python (with values, not just booleans)

• Expression: -1 or (5*5 == 26)
• 5*5 == 26 is False
• -1 is truthy, so the result is -1 (the first truthy value), not a boolean True
• If you cast to bool, bool(-1) is True

3. Bitwise OR in languages like C

• Expression (depending on exact syntax): -1 | (5*5 == 26)
• 5*5 == 26 is 0 (False)
• -1 | 0 yields -1 (since -1 is all bits 1)
• Numeric result: -1

4. Arithmetic check

• 5*5 = 25, so 25 = 26 is false
• The overall truth of the disjunction depends only on -1 being “truthy” in the language

If you can tell me the language (C, Java, Python, etc.) or the exact problem statement, I can give a precise, formatted answer.
