Question 886946
PEMDAS:


{{{-4(1+5)^2/(6•2)}}}Your big dot will not render.  Use an asterisk.


{{{-4(1+5)^2/(6*2)}}}
{{{-4(6)^2/12}}}
{{{-4*36/12}}}
{{{-(4*2*2*3*3)/(2*2*3)}}}----doing this just to see what to cancel
{{{highlight(-12)}}}


It could have been cut to one fewer steps.  Reduction could be done at the second step.
