-1 OR 5*5=25

Result: True (i.e., 1 in most contexts).

Reason:

• In logic/programming, nonzero values are treated as true. Here, -1 is true.
• 5*5 = 25 is also true.
• true OR true = true.

Notes on different languages:

• Python (with or): -1 or (5*5 == 25) would yield -1 (because -1 is the first truthy value).
• C/C++/Java (using ||): true || true yields 1 (true).
• If you intended bitwise OR (-1 | 25), that also results in -1.
