1. Calculate $2027+720:(75-5 \cdot 12)-(3 \cdot 5+5) \cdot 3-2$.
1. \(2027+720:(75-5 \cdot 12)-(3 \cdot 5+5) \cdot 3-2=\)
\(=2027+720:(75-60)-(15+5) \cdot 3-2=1\) BOD
\(=2027+720: 15-20 \cdot 3-2=\quad 1\) BOD
\(=2027+48-60-2=\quad 1\) BOD
\(=2075-60-2=1\) BOD
\(=2015-2=1\) BOD
\(=2013\) 1 BOD
```

TOTAL 6 POINTS
