Let's break down each expression:
a) \( (5 - 181)(-5) - (-7 - |-31|) \)
\( (5 - 181) = -176 \)
\( -176 \times (-5) = 880 \)
\( |-31| = 31 \)
\( -7 - 31 = -38 \)
\( 880 - (-38) = 880 + 38 = 918 \)
So, the answer to (a) is 918.
b) \( -2 \times 113 - 117 \div (-16 + 3) \times (-1) \)
\( -2 \times 113 = -226 \)
\( -16 + 3 = -13 \)
\( 117 \div (-13) = -9 \)
\( -226 \times (-9) = 2034 \)
So, the answer to (b) is 2034.
c) \( 1 - 3 \times (-4) \times 15 - (-2) + 5 \)
\( 3 \times (-4) \times 15 = -180 \)
\( -180 - (-2) = -180 + 2 = -178 \)
\( 1 - 178 + 5 = -172 \)
So, the answer to (c) is -172.
d) \( 1 - 5 \times (-2) + 1 - 5 + 7 \times (-2) \div (-1) \)
\( 5 \times (-2) = -10 \)
\( 1 - (-10) + 1 - 5 + 7 \times (-2) \div (-1) \)
\( 7 \times (-2) = -14 \)
\( -14 \div (-1) = 14 \)
\( 1 - (-10) + 1 - 5 + 14 = 21 \)
So, the answer to (d) is 21.
