Question

why does 3 x -4= 12 and not -12

Answer 1

Answer:

if you have -3×-4=12

Step-by-step explanation:

the reason is that anytime you multiply numbers with negative signs you get a positive value.

In order for you to get a positive number, both numbers you are multiplying must be negative.

But if one of the numbers you are multiplying is a negative and the other number positive then you have a negative value as your answer.

e.g. 3×-4=-12.

Answer 2

For the answer to be -12 the problem would have to be 3×-4=-12.
