Follow Order of Operations: First, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS. We start with the expression inside the parentheses (12-15+3). Calculation: 12 - 15 + 3 = -3 + 3 = 0Calculate Inside Parentheses: Now that we have simplified the expression inside the parentheses to 0, we can proceed with the multiplication part of the expression. We multiply 7 by the result from Step 1. Calculation: 7 * 0 = 0Multiply Result: Finally, we add the result from Step 2 to the number 5, which is outside the parentheses. Calculation: 5 + 0 = 5

5+7 \times (12-15+3)

Follow Order of Operations: First, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS. We start with the expression inside the parentheses $12-15+3$ . $\newline$ Calculation: $12 - 15 + 3 = -3 + 3 = 0$
Calculate Inside Parentheses: Now that we have simplified the expression inside the parentheses to $0$ , we can proceed with the multiplication part of the expression. We multiply $7$ by the result from Step $1$ . $\newline$ Calculation: $7 \times 0 = 0$
Multiply Result: Finally, we add the result from Step $2$ to the number $5$ , which is outside the parentheses. $\newline$ Calculation: $5 + 0 = 5$
