Step 1.2.1

Move the negative one from the denominator of $\frac{f \cdot - 1}{- 1}$ .

$- 1 \cdot (f \cdot - 1) = \frac{4}{- 1}$

Step 1.2.2

Rewrite $- 1 \cdot (f \cdot - 1)$ as $- (f \cdot - 1)$ .

$- (f \cdot - 1) = \frac{4}{- 1}$

Step 1.2.3

Move $- 1$ to the left of $f$ .

$- (- 1 \cdot f) = \frac{4}{- 1}$

Step 1.2.4

Rewrite $- 1 f$ as $- f$ .

$- - f = \frac{4}{- 1}$

Step 1.2.5

Multiply $- - f$ .
