	Example 1.2.5
	$$ Represent the position vector to the point $\left(2\,-3\right)$ in terms of the unit basis vectors i and j. $$ Solution $$ $\left[\begin{array}{c}2\\ -3\end{array}\right]\=2\left[\begin{array}{c}1\\ 0\end{array}\right]-3\left[\begin{array}{c}0\\ 1\end{array}\right]$ = $2 \mathbf{i}-3 \mathbf{j}$  $$
