Factors and multiples
Find $$\displaystyle{4}-{1}{\left(\frac{{1}}{{2}}\right)}$$
We have to find: Find $$\displaystyle{4}-{1}{\left(\frac{{1}}{{2}}\right)}$$
Notice that Find $$\displaystyle{4}-{1}{\left(\frac{1}{{2}}\right)}={4}-{\left({1}+{\left(\frac{1}{{2}}\right)}\right)}={\left({4}-{1}\right)}+\frac{1}{{2}}={3}+{\left(\frac{1}{{2}}\right)}={3}{\left(\frac{1}{{2}}\right)}$$
