Questions: a. (-1) * 2 * 3 b. (-1) * (-2) * 3 c. (-1) * (-2) * (-3)

Transcript text: a. $(-1) \cdot 2 \cdot 3$ b. $(-1) \cdot(-2) \cdot 3$ c. $(-1) \cdot(-2) \cdot(-3)$

Solution

Step 1: Multiply the first two numbers

For part (a), multiply $(-1)$ and $2$: \[ (-1) \cdot 2 = -2 \]

For part (b), multiply $(-1)$ and $(-2)$: \[ (-1) \cdot (-2) = 2 \]

For part (c), multiply $(-1)$ and $(-2)$: \[ (-1) \cdot (-2) = 2 \]

Step 2: Multiply the result by the third number

For part (a), multiply $-2$ by $3$: \[ -2 \cdot 3 = -6 \]

For part (b), multiply $2$ by $3$: \[ 2 \cdot 3 = 6 \]

For part (c), multiply $2$ by $(-3)$: \[ 2 \cdot (-3) = -6 \]

For part (a): $\boxed{-6}$
For part (b): $\boxed{6}$
For part (c): $\boxed{-6}$
