-1 OR 5*5=25

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

1. Boolean logic (logical OR)

• Evaluate: 5*5 = 25 is True.
• -1 is nonzero, so treated as True.
• True OR True => True. Answer: True (often 1 in many contexts).

2. Bitwise OR (as in programming languages like C)

• If you meant -1 | (5*5) (i.e., -1 | 25):
  • -1 has all bits set, so -1 | 25 = -1.
• The expression as written isn’t standard: mixing -1 with a boolean like 5*5=25 isn’t typical. If you meant (-1) | 25, the result is -1.

If you share the language or exact intent (boolean vs bitwise OR), I can give a precise evaluation.
