Final answer:
The question involves using the order of operations to find the value of the expression 15 + (-10) * (-30). After multiplication, the value of (-10)*(-30) is 300. Adding 15 gives a final result of 315.
Step-by-step explanation:
The problem is asking us to find the value of this mathematical expression: 15 + (-10) * (-30). To solve this, we need to follow the order of operations, which is typically remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). The order of operations rule dictates that we should carry out Multiplication before Addition.
So first we calculate the product of -10 and -30, which is 300 because multiplying two negative numbers gives a positive product. Then we proceed to addition: 15 + 300 = 315.
So, the solution to the given numerical expression is 315.
