-16 + а +33 + b - a = (a-a) + b + (33 - 16 ) = b + 1772 - m - n - 89 -11 +m = (-m+m) - n +(72 - 89 - 11) =
= - n + (-28) = - n - 28
-x + y - 3/14 + 2/7 - 5/6 + x = (-x+x) +y + (-3/14 +2/7 - 5/6) =
= y + ( -9/42 + 12/42 - 35/42) = y + ( -32/42) = y - 16/21
p - k + 3/8 - 9/16 + 7/32 - p + k = (p-p) + (-k +k) +(3/8 - 9/16 +7/32)=
= 12/32 - 18/32 + 7/32 = 19/32 - 18/32 = 1/32
