For Question 1, when you multiply two negative numbers, the product is positive. Therefore, the correct response is:
Positive - If the signs of the factors are the same, the product is positive.
For Question 2, to determine the product of -38 and -123, you can calculate it as follows:
\[ -38 \times -123 = 38 \times 123 \]
Calculating \(38 \times 123\):
\[ 38 \times 123 = 4674 \]
Therefore, the simplest form of the product is:
4674
