I need a real world example for multiplying integers?

Question

For example...-4 x -6 = 24. I need a real world example for why two negatives equal a positive.

Answer 1

Well, consider this.

Let's say I have the number 2. If I multiply it by 3, I am going to get six.

Now if I multiply 2 by -3, what will I get? I can't get six, because 2 x 3 = 6. The only logical thing to get is -6.

If I think about -3 as 3 x -1, then I can look at 2 x -3 as 2 x 3 x -1. And then I see that it is the -1 that changes the sign of the answer from 6 to -6.

So, now I know that if I multiply 2 x -3 I get -6. But what happens if I multiply -2 x -3. Well -2 = 2 x -1, by the rule we established above. so this is -1 x 2 x -3, which is -1 x -6. -1 should change the sign of -6 to 6. So -2 x -3 = 6.

Answer 2

if you have a bag with 8 coins and take away -1 coin 4 times in a row, this would mean the same as adding -1 coin -4 times.

you would end up with 12 coins.
12-8= 4, -1 times -4 = 4
