Question

11+8x{45+4x[3+8x(12x13-8x14)-37]}+1234;

Answer 1

11+8x{45+4x[3+8x(12x13-8x14)-37]}+1234 =
=1245+8x{45+4x[3+8x(156-112)-37]} =
=1245+8x[45+4x(8x44-34)]=
=1245+8x[45+4x(352-34)]=
=1245+8x(45+4x318)=
=1245+8x(45+1272) =
=1245+8x1317 =
=1245+10536=11781

(32x15-32x5)+11x12+7x{124-5x[210-2x(23x17-24x12)]} =
=320+132+7x{124-5x[210-2x(391-288)]} =
=452+7x[124-5x(210-2x103)] =
=452+7x[124-5x(210-206)] =
=452+7x(124-5x4) =
=452+7x(124-20) =
=452+7x104 =
=425+728=1180
