Use properties of operations and rules for multiplying signed numbers to multiply −25 by 310

Answer 1

To multiply −25 by 310, we can follow the rule for multiplying signed numbers.

Step 1: Multiply the absolute values of the numbers - 25 and 310.
|-25| * |310| = 25 * 310 = 7750

Step 2: Determine the sign of the product.
To determine the sign, we use the rule that states that the product of two numbers with different signs is negative. Since −25 is negative and 310 is positive, the product will be negative.

Step 3: Hence, −25 multiplied by 310 equals −7750.
