Question

What is `7\times ( - 7)`?

Answer 1

The answer is -49.

Explanation:

When you multiply integers, there are a few rules. First, when you multiply a positive number by a negative number, the answer will always be negative. But, when you multiply a positive by a positive or a negative by a negative, the answer will always be positive.

Answer 2

`7xx(-7)=color(blue)(-49)`

Explanation:

One way to think about this is to consider positive numbers as money I actually have and negative numbers as amounts I owe to other people.
Then if I owed `$7` to `7` people
then I would have `7xx(-7)=-49`; that is I would owe a total of `$49` dollars
