Question:
If $\overrightarrow{\mathrm{a}}=(\hat{\mathrm{i}}-2 \hat{\mathrm{j}}), \overrightarrow{\mathrm{b}}=(2 \hat{\mathrm{i}}-3 \hat{\mathrm{j}})$ and $\overrightarrow{\mathrm{c}}=(2 \hat{\mathrm{i}}+3 \hat{\mathrm{k}})$, find $(\overrightarrow{\mathrm{a}}+\overrightarrow{\mathrm{b}}+\overrightarrow{\mathrm{c}})$
Solution:
