Okay, we want to determine whether the answer will be positive, negative 0, or undefined.
00:05
So the product of two numbers that have opposite signs.
00:08
So that means one of the numbers is positive, one of the numbers is negative, and when i multiply a positive with a negative, the answer is a negative.
00:16
Okay, so it will be negative.
00:18
The product of 99 negative numbers.
00:20
So when i multiply a negative and a negative becomes positive, but then when i multiply that positive with a negative, it becomes negative.
00:30
So if i have an even number of negatives, then they can.
00:33
Can become positives, but if i have an odd number of negatives, then it will end up negative.
00:38
So this is an odd number of negative, so it will end up negative...
