-1" OR 3*2>5 --

What you posted looks like a typical SQL injection payload, not a math problem.

• 32 > 5 evaluates to true (since 32 = 6 and 6 > 5 is true).
• The -- at the end is a SQL comment marker, so anything after it is ignored.
• The -1" part is likely closing a string literal in the vulnerable input; the exact effect depends on the surrounding SQL.

In short, this kind of input is designed to make a condition evaluate to true (because True OR anything is True) and to comment out the rest of the statement. This is a basic concept behind tautologies used in SQL injection.

If you’re studying for exams, I can help with:

• Truth tables and short-circuit evaluation of OR/AND
• How SQL injection works at a high level (without how-to exploit)
• Safe, exam-focused practice problems on boolean logic

Would you like a quick, safe practice problem set on boolean logic or truth tables?
