\[\overrightarrow{a} + \overrightarrow{b} = \ ?\]

\[\textbf{а)}\ \overrightarrow{a}\ \left\{ 3;2 \right\};\ \overrightarrow{b}\ \left\{ 2;5 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} + \overrightarrow{b}\ \left\{ 5;7 \right\}.\]

\[Б)\ \overrightarrow{a}\ \left\{ 3; - 4 \right\};\ \overrightarrow{b}\ \left\{ 1;5 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} + \overrightarrow{b}\ \left\{ 4;1 \right\}.\]

\[\textbf{в)}\ \overrightarrow{a}\ \left\{ - 4; - 2 \right\};\ \overrightarrow{b}\ \left\{ 5;3 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} + \overrightarrow{b}\ \left\{ 1;1 \right\}.\]

\[Г)\ \overrightarrow{a}\ \left\{ 2;7 \right\};\ \overrightarrow{b}\ \left\{ - 3; - 7 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} + \overrightarrow{b}\ \left\{ - 1;0 \right\}.\]
