Great thinking anon, are you the same anon that posted the question ??

I love this trick question  !!!

I just added it into the puzzles sticky thread :))

hi Josh4444,

That is not quite right.  

it is not 9000 at all because the nine is not in the thousands column, it is in the tenths column.

The number is

One hundred and thirty point nine four seven one.

I shall give you 3 points for your genuine attempt

xy+2=12\\
xy=10\\$$

This is the formula for a hyperbola.  It will be in the 1st and 3rd quadrants.

$${\mathtt{8.9}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{67}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{60}}}}\right)} = {\mathtt{8.195\: \!524\: \!773\: \!254\: \!9}}$$
