$\frac{-35}{6}$ or $\frac{35}{-6}$

Note that, although $-\frac{35}{6}$, $\frac{-35}{6}$, and $\frac{35}{-6}$ all evaluate to the same number (approximately $-5.83$), they each mean something different ("the negative of thirty-five sixths" versus "negative thirty-five, divided by six" versus "thirty-five divided by negative six").
