How do you multiple negative and positive numbers?

To multiply negative and positive numbers together, multiply the numbers as usual, and then add a negative sign to the answer. This is because the product of a negative and a positive number multiplied together is always negative.

In mathematics there are a few simple rules of thumb to remember when multiplying numbers. First, the product of two positive numbers is always positive, so 3 x 2 = 6. Next, the product of two negative numbers is always positive, so -3 x -2 = 6. Finally, the product of one negative and one positive is always negative. An example of this is -3 x 2 = -6.
