344. \( -(-[-(-1 \cdot 3 \cdot 2-15) \div 3]+2)-1 \) \( 345 .[-4 \cdot(4+3)+(1-4 \cdot 9)]-(-11) \)

To solve the first expression \( -(-[-(-1 \cdot 3 \cdot 2-15) \div 3]+2)-1 \), we start by calculating the innermost part: - Calculate \( -1 \cdot 3 \cdot 2 = -6 \). - Now compute \( - (-6 - 15) = -(-21) = 21 \). - Now we divide \( 21 \div 3 = 7 \). - Next, evaluate \( -(-[7]+2) = -(-5) = 5 \). - Finally, subtract \( 5 - 1 = 4 \). The answer to the first expression is \( 4 \). For the second expression \( [-4 \cdot(4+3)+(1-4 \cdot 9)]-(-11) \): - First, calculate \( 4 + 3 = 7 \) so \( -4 \cdot 7 = -28 \). - Now calculate \( 1 - 4 \cdot 9 = 1 - 36 = -35 \). - Combine these results: \( -28 - 35 = -63 \). - Finally, simplify: \( -63 - (-11) = -63 + 11 = -52 \). The answer to the second expression is \( -52 \).
