Answer 1

$5 - (a + 3) = 5 - a - 3 = 2 - a$
$8 - (10 + b) = 8 - 10 - b = - 2 - b \ 9 - (c + 7) = 9 - c - 7 = 2 - c$
$2 + ( - 8 + c) = 2 - 8 + c = - 6 + c \ 3 + ( - d - 5) = 3 - d - 5 = - 2 - d$
$4 + (a - 9) = 4 + a - 9 = - 5 + a \ 0.8 - (m + 3) = 0.8 - m - 3 = - 2.2 - m$
$1.4 + (n - 2) = 1.4 + n - 2 = - 0.6 + n \ 2.6 - ( - k + 10) = 2.6 + k - 10 = - 7.4 + k$
