Question

18 integers are multiplled together What will be the sign If their product if IS of them are negative and 3 ofthem are pcsltive?​

Answer 1

If 15 of them are negative, then the sign of their product will be negative...

If 12 of them are positive, then the sign will be positive

Remember, while solving questions like these, ignore the no. of positive integers...

If the no. of negative integers is even, all of them will cancel out, hence the answer is positive...

if the no. of negative integers is odd, then one remains negative, hence the product is negative...

Answer 2

Answer:

negative

Step-by-step explanation:
