Answer:
a negative integer
Step-by-step explanation:
We can first establish basic rules that we can apply:
the product of one negative integer:
-1 = -1
(odd number = negative)
the product of two negative integers:
-1 · -1 = 1
(even number = positive)
the product of three negative integers:
-1 · -1 · -1 = 1 {-1 · -1 = 1, 1 · -1 = -1}
(odd number = negative)
the product of four negative integers:
-1 · -1 · -1 · -1 = 1
(even number = positive)
So, we can understand that an even number of integers changes the original value to its negative/positive [the opposite +/- sign from the original number], whilst an odd number of integers does not change the +/- sign.
So, because 23 is an odd number, the product will stay negative.
