Just type this directly into the calculator (using parentheses for the trig arguments):
$${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{451}}{\mathtt{\,-\,}}{\mathtt{52}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{30}}^\circ\right)}{\mathtt{\,\times\,}}{cot}{\left({\mathtt{10}}\right)} = {\mathtt{305.546\: \!672\: \!690\: \!029\: \!848\: \!8}}$$
