-4-11-20 (-22 (-2) - 15 - (10+7.2) - (8-5) - 1) + 11=-160

Steps

-4-11-20 (-22 (-2) - 15 - (10+7.2) - (8-5) - 1) + 11

20 (-22 (-2) - 15 - (10+7.2) - (8-5) - 1)

= 20 (2*22-1-15 - (10+7.2) - (8-5))

= 20 (44-1-15 - (10+7.2) - (8-5))

= 20 (44-1-3-15-17.2)

= 20*7*8

= 156

= - 4-11-156+11

= - 160
