Simplify: 18−2⋅3+6^2/2 .

Answer 1

To simplify the given expression, we can follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

First, we have to deal with the exponentiation: 6^2 = 36.

Now our expression becomes: 18 - 2 x 3 + 36/2

Next, we perform the multiplication: 2 x 3 = 6.

Our expression now simplifies to: 18 - 6 + 36/2

We can now perform the division: 36/2 = 18.

Our expression becomes: 18 - 6 + 18

Finally, we perform the subtraction: 18 - 6 = 12.

Our final simplified expression is: 12 + 18 = 30.
