Determine the sign of the product of −10.4×−78.2

Question

. Enter + for positive or ­­­– for negative.(

Answer 1

To determine the sign of the product of two numbers, we can follow this rule:

• The product of two positive numbers is positive.
• The product of two negative numbers is also positive.
• The product of one positive and one negative number is negative.

In this case, both numbers \(-10.4\) and \(-78.2\) are negative. Therefore, their product will be positive.

Thus, the sign of the product \(-10.4 \times -78.2\) is +.
