Answer 1

$3 \times ( - 7) + 2 \times ( - 4) - ( - 5) \times ( - 3) = - 21 - 8 + 5 \times ( - 3) = - 21 - 8 - 15 = - 44$

$- 4 + ( - 9) \times ( - 5) = - 4 + 45 = 41$

$512 \times ( - 105) + 205 \times 512 = - 512 \times 105 + 205 \times 512 = 512( - 105 + 205) = 512 \times 100 = 51200$

$8888 \times ( - 296) + 8888 \times 196 = - 8888 \times 296 + 8888 \times 196 = 8888( - 296 + 196) = 8888 \times ( - 100) = - 888800$
