36+36-2*6*6*(-1/2)

Let's solve the expression step by step.

The expression is:

\( 36 + 36 - 2 \times 6 \times 6 \times \left(-\frac{1}{2}\right) \).

1. First, calculate the multiplication: \[ 2 \times 6 = 12, \] \[ 12 \times 6 = 72, \] thus, \[ 72 \times \left(-\frac{1}{2}\right) = -36. \]

2. Now, substitute back into the original expression: \[ 36 + 36 - (-36). \]

3. This simplifies to: \[ 36 + 36 + 36 = 108. \]

Therefore, the final result is \( 108 \).
