Question

(32 x 15 - 32 x 5) +11 x 12 +7 x {124 -5 x [210-2 x (23 x 17 - 24 x 12)]}

Answer 1

(32 x 15 - 32 x 5) +11 x 12 +7 x {124 -5 x [210-2 x (23 x 17 - 24 x 12)]} =
= 32 × (15 - 5) + 132 + 7 × {124 -5 x [210-2 x (391 - 288)]} =
= 320 + 132 + 7 × [124 - 5 × ( 210 - 2 × 103)] =
= 452 + 7 × [124 - 5 × ( 210 - 206)] =
= 452 + 7 × ( 124 - 5 x 4) =
= 452 + 7 × 104 = 452 + 728 = 1180

Answer 2

(480-160)+11x12+7x{124-5x[210-2x(391-288)=
320+11x12+7x[124-5x[210-2x103]=
320+11x12+7x(124-5x(210-206)=
320+132+7x(124-5x4)=
320+132+7x(124-20)=
320+132+7x104=
320+132+728=1180
