What is the input method for mixed numbers on this calculator. If you want to just do a single variable and turn it into a decimal or simplify?
Just enter, for example, 3 + 1/2 and press =
$${\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\frac{{\mathtt{7}}}{{\mathtt{2}}}} = {\mathtt{3.5}}$$
