The sign of the product for this problem will be positive.

We know this because when multiplying more than one number, we can find positive or negative based on how many negatives there are. If there are an even number of negatives numbers, then it should be a positive solution. If there is an odd number of negatives, then there should be a negative solution.

Since there are 4 negatives in this problem, we know the answer is positive

Answer:

Sam

Step-by-step explanation:

Sam made a mistake when he said $10^2 -20$ . The steps should have been:

$2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30$

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
