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

\[А)\ \overrightarrow{a}\ \left\{ 5;3 \right\};\ \overrightarrow{b}\ \left\{ 2;1 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} - \overrightarrow{b}\ \left\{ 3;2 \right\}.\]

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

\[\Longrightarrow \ \overrightarrow{a} - \overrightarrow{b}\ \left\{ 6;0 \right\}.\]

\[\textbf{в)}\ \overrightarrow{a}\ \left\{ 3;6 \right\};\ \overrightarrow{b}\ \left\{ 4; - 3 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} - \overrightarrow{b}\ \left\{ - 1;9 \right\}.\]

\[Г)\ \overrightarrow{a}\ \left\{ - 5; - 6 \right\};\ \overrightarrow{b}\ \left\{ 2; - 4 \right\} \Longrightarrow \ \]

\[\Longrightarrow \ \overrightarrow{a} - \overrightarrow{b}\ \left\{ - 7; - 2 \right\}.\]
