1. Calculate: $1325: 5+15: 5-(99-9: 9) \cdot 2-35-30$.
1. Calculate: $1325: 5+15: 5-(99-9: 9) \cdot 2-35-30$.

## Solution.

$$
\begin{aligned}
& 1325: 5+15: 5-(99-9: 9) \cdot 2-35-30 \\
& =265+3-(99-9: 9) \cdot 2-35-30 \quad 1 \text { POINT } \\
& =265+3-(99-1) \cdot 2-35-30 \quad 1 \text { POINT } \\
& =268-98 \cdot 2-35-30 \quad 1 \text { POINT } \\
& =268-196-35-30 \quad 1 \text { POINT } \\
& =72-35-30 \quad 1 \text { POINT } \\
& =37-30 \\
& =7 \quad 1 \text{POINT} \\
& \text { TOTAL } 6 \text { POINTS }
\end{aligned}

Note: If a student incorrectly copies part of the problem or makes a calculation error, points are deducted for that part, and further scoring follows the principle of "following the error."
