To determine the sign of the product of two numbers, we need to look at the signs of the individual numbers:
- The first number is \(-0.708\), which is negative.
- The second number is \(-6.24\), which is also negative.
When you multiply two negative numbers together, the result is positive.
Thus, the sign of the product \(-0.708 \times -6.24\) is:
positive.
