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 parentheses.Calculate the expression inside the parentheses: (1+2).1+2=3
Calculate Parentheses: Now that we have the result from the parentheses, we substitute it back into the original expression.The expression now is 6÷2×3.
Substitute Result: Next, we perform the division and multiplication from left to right as they appear in the expression.First, divide 6 by 2.6÷2=3
Perform Division and Multiplication: Now, multiply the result from Step 3 by the value we obtained from the parentheses.3×3=9
