Question

subtract.
3 - 9 = 6

Explanation:

Step1: Recall subtraction rules

For \(3 - 9\), since \(9>3\), we can rewrite it as \(-(9 - 3)\).

Step2: Calculate \(9 - 3\)

\(9-3 = 6\), so \(-(9 - 3)=- 6\). So the correct result of \(3 - 9\) is \(-6\), not \(6\).

Answer:

The correct answer is \(-6\) (the original answer \(6\) is incorrect, the correct calculation gives \(3 - 9=-6\)).
