\[\boxed{\mathbf{767\ (767)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)}\ 18 - 12 - 26 = 18 + ( - 12) + ( - 26) = 18 + ( - 38) = - 20\]

\[\textbf{б)} - 13 - 8 + 13 = - 13 + ( - 8) + 13 = 0 + ( - 8) = - 8\]

\[\textbf{в)} - 1 + 2 - 3 = - 1 + 2 + ( - 3) = 1 + ( - 3) = - 2\]

\[\textbf{г)}\ 5 - 13 + 8 = 5 + ( - 13) + 8 = 13 + ( - 13) = 0\]

\[\textbf{д)}\ 5 + 6 - 17 = 5 + 6 + ( - 17) = 11 + ( - 17) = - 6\]

\[\textbf{е)} - 7 - 3 - 11 = - 7 + ( - 3) + ( - 11) = - 10 + ( - 11) = - 21\]
