ГДЗ по математике 6 класс Дорофеев Задание 897

\[\boxed{\mathbf{897\ (897)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)}\ |3| + |7| = 3 + 7 = 10;\ \ \ |3 + 7| = |10| = 10.\]

\[Значит:\ \ |3| + |7| = |3 + 7|.\]

\[\textbf{б)}\ | - 1| + |10| = 1 + 10 = 11;\ \ \ \left| ( - 1) + 10 \right| = |9| = 9.\]

\[Значит:\ \ | - 1| + |10| > \left| ( - 1) + 10 \right|.\]

\[\textbf{в)}\ | - 6| + |5| = 6 + 5 = 11;\ \ \left| ( - 6) + 5 \right| = | - 1| = 1.\]

\[Значит:\ \ | - 6| + |5| > \left| ( - 6) + 5 \right|.\]

\[\textbf{г)}\ | - 5| + | - 8| = 5 + 8 = 13;\ \ \ \left| ( - 5) + ( - 8) \right| = | - 13| = 13.\]

\[Значит:\ \ | - 5| + | - 8| = \left| ( - 5) + ( - 8) \right|\text{.\ }\]
