To find the value of -2(3.1), you need to multiply -2 by 3.1. The general rule for multiplying rational numbers is that if the signs are the same (either both positive or both negative), the product will be positive. If the signs are different (one positive and one negative), the product will be negative.
In this case, -2 is negative and 3.1 is positive. Therefore, the product of -2 and 3.1 will be negative.
To calculate -2(3.1), multiply the absolute values of the numbers and then apply the sign:
|-2| × |3.1| = 2 × 3.1 = 6.2
Since the signs are different (negative and positive), the final answer will be negative:
-2(3.1) = -6.2
