1.\(\ \ \ \)\( {2} ^ {2} - {3} \cdot {(-3)} - {} \sqrt {4} = \)
\( 11 \).
2.\(\ \ \ \)\( {(-36)} : {(-6)} - {(-6)} {} - {(-15)} : {5} = \)
\( 15 \).
3.\(\ \ \ \) \(\big((-256)+243\big)\cdot\big((-7)+8\big)+1\cdot4-\big((-31)+27\big) =\)
\( -5 \).
4.\(\ \ \ \) \(972:243\cdot\big((-36)+9\big):\Big(\big((-8)-(-9)\big)\cdot72:8\Big) =\)
\( -12 \).
5.\(\ \ \ \) \((-1)^{1}\cdot1\cdot(-128):\Big(1\cdot(-1)\cdot\big((-275)-(-243)\big)\Big) =\)
\( 4 \).
6.\(\ \ \ \) \((-5)^{1}\cdot\big((-80)-(-81)\big)-(-1)^{1}\cdot1\cdot16 =\)
\( 11 \).
