Question

multiply: -2 × -7 = \boxed{}

Explanation:

Step1: Recall sign rule for multiplication

When multiplying two negative numbers, the result is positive. The rule is $(-a) \times (-b) = ab$ where $a$ and $b$ are positive numbers.

Step2: Apply the rule to the given numbers

Here, $a = 2$ and $b = 7$. So, $-2\times -7=2\times7$.

Step3: Calculate the product of 2 and 7

$2\times7 = 14$.

Answer:

14
