#204/-52 or -3.92307...#

Follow BEDMAS (bracket, exponent, division, multiplication, addition, subtraction.)

Let’s solve the brackets first, so

#((20(15-4)-4(8-4)))/((10(2-6)-2(4+2)))#

#=((20(11)-4(4)))/((10(-4)-2(6)))#

Now lets multiply where needed.

#= (((220)-(16)))/(((-40)-(12)))#

Then subtraction/addition

# = ((204))/((-52))=-3.9230769231#
