Question

remember, multiplying a positive number and a negative number gives you a negative product. 7·(-5) 9·5 -9·5 45 -45 -35

Explanation:

Step1: Calculate $7 \cdot (-5)$

Multiply positive 7 by negative 5. Since positive × negative = negative, compute $7 \times 5 = 35$, then apply the negative sign: $7 \cdot (-5) = -35$

Step2: Calculate $9 \cdot 5$

Multiply two positive numbers. Positive × positive = positive, so $9 \times 5 = 45$

Step3: Calculate $-9 \cdot 5$

Multiply negative 9 by positive 5. Negative × positive = negative, compute $9 \times 5 = 45$, then apply the negative sign: $-9 \cdot 5 = -45$

Answer:

$7 \cdot (-5)
ightarrow -35$
$9 \cdot 5
ightarrow 45$
$-9 \cdot 5
ightarrow -45$
