Question 519330
-12/3/4
<pre>
I can't tell whether that means {{{((-12)/3)/4}}} or {{{(-12)/(3/4)}}}

If it means 

{{{((-12)/3)/4}}} then we do the top part {{{(-12)/3}}} and get -4. Then we have

 {{{(-4)/4}}} and the answer is 

-1

However, if it means {{{(-12)/(3/4)}}} then we make it into a division

-12 ÷ {{{3/4}}} and then invert the second and multiply

-12 × {{{4/3}}} and the answer is

-16
