-1 OR 5*5=25 --

Here’s the gist, assuming the intended grouping is (-1) OR (5*5 = 25):

• 5*5 = 25 is true.
• -1 is nonzero, so considered true in most languages.

So true OR true -> true.

Language-specific notes:

• C/C++: evaluates to 1 (true).
• Python: -1 is truthy; the expression (-1) or (5*5 == 25) yields -1.
• JavaScript: -1 is truthy; -1 || (25 == 25) yields -1.

If you tell me the exact language (or if you want the boolean value only), I can tailor the answer.
