Add two negative numbers:
Think of -1 as a debt. I owe you $1. We bet a dollar on a football game and I win----> that's -1 minus 1 or -1-1 or ZERO. (I explain subtracting/adding numbers this way to simplify before we move on to multiplication/division).
Multiply two negative numbers:
Let's say I owe you $2. I have -$2, right? Assume you also owe me $2. In terms of each other, we both have -$2, ok?
We decide to go double or nothing on the following two football games (two GROUPS of -$2) I win the first game---> now I have zero, you still owe me two. I win the second game---> I still have $0, my debt is still clear and now you owe me $4, or -$4 for you....
Therefore negative 2 groups of negative 2 = a positive 4. Why---> I started at -2 and added two Groups of TWO to my amount, when we settle up. I will have gone from -$2 to +$2---> a net gain of FOUR or +4
---> (-2)(-2) = +4

What are the rules for multiplying positive and negative numbers?
When multiplying numbers, the rules for signs are straightforward: the product of two positive numbers is positive, and the product of two negative numbers is also positive. However, when multiplying a positive number by a negative number, the result is negative. In summary, multiplying numbers with the same sign yields a positive result, while multiplying numbers with different signs results in a negative product.
Multiplying an even number of negative numbers gives an answer that is?
Multiplying an even number of negative numbers results in a positive number. This is because each pair of negative numbers multiplies to give a positive product, and with an even count, all pairs will cancel out the negativity. Therefore, the final result will be positive.
What is the sign for multiplication and addition?
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value.

What does multiplying integers mean?
Multiplying integers involves combining two or more whole numbers to find their total as a repeated addition. For example, multiplying 3 by 4 means adding 3 a total of 4 times (3 + 3 + 3 + 3), resulting in 12. The product of two integers can be positive or negative, depending on the signs of the integers involved: multiplying two positive or two negative integers results in a positive product, while multiplying one positive and one negative integer results in a negative product.
What does negative one times negative twelve equals?

Why multiplying 3 negative integers results in a negative answer?
when you multiply 2 of them it's positive, 3 and it stays negative.
When you take a negative number to an odd power you get a negative answer Why do you get a positive answer when you take an odd number to an even power?
When you raise a negative number to an odd power, the multiplication of an odd number of negative factors results in a negative product. In contrast, raising a negative number to an even power involves multiplying it by itself an even number of times, which pairs up the negative factors to yield a positive product. This is due to the fact that multiplying two negative numbers produces a positive result. Thus, the overall effect of multiplying an even number of negative factors is positive.
What is the rule for multiplying different sign integers?
When multiplying integers with different signs, the rule is that the product will always be negative. For example, multiplying a positive integer by a negative integer results in a negative product. Conversely, multiplying a negative integer by a positive integer also yields a negative result. In summary, if the signs of the integers differ, the product is negative.
When is the product of two integers a positive?
The product of two integers is positive when both integers are either positive or both are negative. For example, multiplying 3 (positive) by 4 (positive) yields 12, while multiplying -3 (negative) by -4 (negative) also results in 12. In contrast, if one integer is positive and the other is negative, the product will be negative.
