-1' OR 3*2>5 --

That looks like an SQL injection payload rather than a normal math problem.

• The part 3*2>5 equals 6>5, which is true.
• In boolean terms, true OR something is true, so the boolean outcome would be true if the syntax were valid.

However, as written it’s not valid SQL: -1' introduces a stray quote and -- starts a comment. In a real database, this would likely cause a syntax error or, if injected into vulnerable code, could alter how a query is evaluated.

If you’re studying for an exam, the key takeaway is:

• 3*2>5 evaluates to true.
• In boolean logic, true OR X = true.
• In SQL, such input is dangerous and should be mitigated with prepared statements and proper input handling. If you want, I can help with defensive strategies or parsing such expressions in a safe, classroom context.
