-2(0,6*20,25)+(0,6*20,25*1)

To solve the expression \(-2(0,6 \times 20,25) + (0,6 \times 20,25 \times 1)\), let's break it down:

1. \((0,6 \times 20,25)\):
   \(0.6 \times 20.25 = 12.15\)

2. Evaluate \(-2 \times 12.15\):
   \(-2 \times 12.15 = -24.3\)

3. Evaluate \(0.6 \times 20.25 \times 1\):
   \(12.15 \times 1 = 12.15\)

4. Add the results:
   \(-24.3 + 12.15 = -12.15\)

So, the value of the expression is \(-12.15\).
