Why does multiplying two negative numbers equal a positive number?

In: 1210

Answer 1

So -5 x -6 = 30

If we talk about money that could be described as: I remove $5 dollars of debt 6 times. That means I have $30 less debt which is also known as “having $30 more dollars.”

Removing it six times is a -6 and five dollars in debt is a -5

That’s how I’ve always thought of it anyway, “removing” negatives a given number of times.
