The produt of two negative numbers is positive
The produt of a positive number and a negative number is negative
Thus, for the product of (8)(-23)(- 21)(-29),
the product of 8 and - 23 would be negative(positve and negative numbers)
the product of - 21 and - 29 would be positive(negative and negative numbers)
Thus, the product of the negative and positive results would be negative. Thus, the correct option is the last option
