-1" OR 3*2>5 --

It looks like an SQL-injection style fragment rather than a pure math expression. If we treat 3*2>5 as a boolean:

• 3*2 > 5 → 6 > 5 → true

The rest ( -1" and the trailing -- ) would depend on context:

• The -1" could be closing a string literal, which is what an attacker attempts in injections.
• The -- at the end is a SQL comment, which tells the engine to ignore the rest of the statement.

So, in a SQL WHERE clause, an injection of this form could make the condition evaluate to true (because OR true is authoritative), and the comment would truncate the rest of the clause.

For exam prep and safety:

• If you’re studying boolean logic: treat 3*2>5 as true. The overall truth would depend on the surrounding operators and parentheses.
• If you’re studying database security: this illustrates why you should use parameterized queries/prepared statements to avoid injection, and validate/sanitize inputs.

Would you like a quick, formal boolean evaluation example, or a safety-focused explanation about preventing SQL injection?
