Answer:
-15
Explanation:
-3 multiplied by 5 is equal to -15. When multiplying two numbers with different signs, the product will always be negative. In this case, -3 is a negative number and 5 is a positive number. Thus, their product will be negative. To calculate the product, we simply need to multiply the absolute values of the two numbers and then add the negative sign as the result. The absolute value of -3 is 3, and the absolute value of 5 is 5, so 3 multiplied by 5 is 15. Adding the negative sign gives us the answer of -15.
