The product of 18 integers is one, is it possible for their sum to be equal to 0? Why or why not?

Yes it can be possible that the product of 18 integers is one and their sum can be zero ,

for example ,

let's take that integers 1&-1

1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1

so in this the product will be 1 nd

sum will be 0

hope it's helpful to you

if I'm wrong I'm sorry

x=9

step-by-step explanation:

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
