You multiply the numbers just like you would normally except that the product will have a negative sign. Example: -6 X 5 = -30. When you multiply a negative number and a positive number, the product will always be negative. Multiplying two positive numbers or two negative numbers will give you positive products.

To get negative four, you can multiply any pair of numbers where one is negative and the other is positive. For example, -2 and 2 multiply to give -4, as do -1 and 4, or -4 and 1. Additionally, you could also use decimal numbers, such as -0.5 and 8, to achieve the same result.
