Answer 1

$( - 1) \times (3 + 9 - 4 + 8) \div ( - 5 + 4 + 2 - 3) = ( - 1) \times 16 \div ( - 2) = 1 \times 16 \div 2 = 16 \div 2 = 8$

$1 + ( - 6 + 8 - 5 - 1) \div ( -2 + 3 + 4 - 6) = 1 - 4 \div ( - 1) = 1 + 4 = 5$

$(3 - 8 - 2 + 4) \div ( - 1 - 6 + 3 + 5) - 2 = - 3 \div 1 - 2 = - 3 - 2 = - 5$

$- 9 - ( - 7 + 3 + 9) \div (1 - 8 + 2) = - 9 - 5 \div ( - 5) = - 9 + 1 = - 8$
