Question

》(-7)×(-10)=

Explanation:

Step1: Recall the rule for multiplying two negative numbers.

When multiplying two negative numbers, the result is positive. The formula for multiplying two negative integers \( (-a) \times (-b) \) (where \( a \) and \( b \) are positive integers) is \( (-a) \times (-b)=a\times b \).

Step2: Apply the rule to the given numbers.

Here, we have \( (-7)\times(-10) \). Using the rule above, we can rewrite this as \( 7\times10 \).

Step3: Calculate the product of 7 and 10.

\( 7\times10 = 70 \).

Answer:

70
