+118608 You can think about negative numbers as cold numbers and positive numbers as hot numbers.
If you take away cold out of a room then the room will get hotter. so - - = +
$${\mathtt{\,-\,}}{\frac{{\mathtt{16}}}{{\mathtt{3}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{7}}$$
the sign always belongs to the number or letter behind it so our 2 terms here are -16/3 and +7
It will look more normal if you swap them around
$${\mathtt{7}}{\mathtt{\,-\,}}{\frac{{\mathtt{16}}}{{\mathtt{3}}}}$$
= $${\mathtt{7}}{\mathtt{\,-\,}}\left({\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)$$
7-5 is 2 Mmm it will have to be smaller than that because you are taking away more than 5.
= $${\mathtt{2}}{\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{3}}}}$$
It will have to be 1 and a bit. There are 3 thirds in a whole. ...
$$=1\frac{2}{3}$$
