\[ 3 - \frac{3}{3} - 1 = 1 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{1}\), \(\frac{-3}{3}\), and \(\frac{-1}{1}\) is \(3\). \[ \begin{aligned} 3 - \frac{3}{3} - 1 &= \frac{3 \cdot 3}{1 \cdot 3} + \frac{-3 \cdot 1}{3 \cdot 1} + \frac{-1 \cdot 3}{1 \cdot 3} \\ &= \frac{9 + -3 + -3}{3} \\ &= \frac{3}{3} \\&= 1 \end{aligned} \]
