\( {\rm{2}}({\rm{5}} - \sqrt {{\rm{16}}} ) \div ({\rm{14}} - {\rm{12}}) \times {\rm{3}} = ?\)

First perform the operation inside parentheses. This gives \(2(5-\sqrt{16}) \div(14-12) \times 3=2(5-4) \div(14-12) \times 3=2(1) \div 2 \times 3=2 \div 2 \times 3\)
Now do the multiplications and divisions from left to right: \({\rm{2}} \div {\rm{2}} \times {\rm{3}} = 1 \times 3 = 3\)
