-1 OR 5*5=25

Result: True (i.e., 1)

Explanation:

• 5*5 = 25 is true.
• -1 is nonzero, so it’s truthy in most languages with C-like truth values.
• True OR True = True.

Note: in Python, the expression -1 or (5*5==25) would yield -1 because -1 is truthy and or returns the first truthy value. If you want Python-specific detail, tell me and I’ll adapt.
