Choose nineteen 10's and one -10
So, the product = [(10)^19][-10]
Notice that [(10)^19] is POSITIVE, which means [(10)^19][-10] is NEGATIVE.
So, [(10)^19][-10] = [(10)^19][-1][10]
= -(10)^20
= E
So, we have:
QUANTITY A: -(10)^20
QUANTITY B: 0
Answer: B

So, we have:
QUANTITY A: -(10)^20
QUANTITY B: 0
Answer: B
I'm a bit confused when it says "consecutive integers". How can the set contains nineteen 10s and one (-10) if they are consecutive integers?
