Explanation:
To multiply integers with different signs:
Multiply the absolute values of the integers.
The product is negative if the signs of the integers are different.
The product is positive if the signs of the integers are the same.
Example: (-3) x 4 = -12
The absolute values of -3 and 4 are 3 and 4.
Multiply 3 and 4 to get 12.
The signs of -3 and 4 are different (one negative and one positive).
Therefore, the product is negative (-12).
