20×(12÷2 + 7) - 18 =

Explanation:

Step1: Calculate inside the parentheses

First, we solve the operations inside the parentheses. According to the order of operations (PEMDAS/BODMAS), we perform division first and then addition.
The expression inside the parentheses is \(12\div2 + 7\).
\(12\div2 = 6\), then \(6 + 7 = 13\). So now the expression becomes \(20\times13 - 18\).

Step2: Perform the multiplication

Next, we perform the multiplication operation. \(20\times13 = 260\). Now the expression is \(260 - 18\).

Step3: Perform the subtraction

Finally, we subtract 18 from 260. \(260 - 18 = 242\).

Answer:

242
