simplify 18 - 2*3 plus 6^2/2
To simplify the expression 18 - 2 * 3 + 6^2 / 2, we follow the order of operations (also known as PEMDAS).
First, we perform exponentiation: 6^2 = 36.
Then, we divide 36 by 2: 36 / 2 = 18.
Next, we perform multiplication: 2 * 3 = 6.
After that, we do addition and subtraction from left to right: 18 - 6 + 18.
Finally, we combine the remaining operations: 18 - 6 + 18 = 30.
Therefore, the simplified expression is 30.
