There is only one common factor.....1
Uh.....you put commas, not decimal points
$${\mathtt{31}}{\mathtt{\,\small\textbf+\,}}{\mathtt{18}}{\mathtt{\,\small\textbf+\,}}{\mathtt{15}}{\mathtt{\,-\,}}{\mathtt{4}} = {\mathtt{60}}$$
That's awesome dude! Pitbull? I've got cats, not dogs........and a rabbit!
Don't know
BOOM BOOM BOOM!!! WOOT WOOT!!!!
WOOOOOHOOOOOOOOOO!!!!
$$\left({\frac{{\mathtt{22}}}{{\mathtt{51}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{17}}}{{\mathtt{22}}}}\right) = {\frac{{\mathtt{1}}}{{\mathtt{3}}}} = {\mathtt{0.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
$${\left({{\mathtt{11}}}^{-{\mathtt{4}}}\right)}^{-{\mathtt{6}}} = {\mathtt{9\,849\,732\,675\,807\,611\,094\,711\,841}}$$
Show them this:
Well, 7+9=16
And I also know 7*9=63
