5*60-140:2+18

To solve the expression \(5 \times 60 - 140 \div 2 + 18\), we follow the order of operations (PEMDAS/BODMAS).

1. Multiplication: \(5 \times 60 = 300\)

2. Division: \(140 \div 2 = 70\)

3. Subtraction and Addition: Now, we have \(300 - 70 + 18\).

   First, perform the subtraction: \[ 300 - 70 = 230 \]

   Then, add \(18\): \[ 230 + 18 = 248 \]

So, the result of \(5 \times 60 - 140 \div 2 + 18\) is \(248\).
