Answer 1

-5+(15÷3)(18÷6)-{4+3(8+2)+15-[13+20-35-(12-5)÷1]-3}-1

=$-5+5\left(18\div \:6\right)-4+3\left(8+2\right)+15-\left[13+20-35-\left(12-5\right)\div \:1\right]-3-1\\\\=-5+5\cdot \:3-4+3\cdot \:10+15-\left[13+20-35-\left(12-5\right)\div \:1\right]-3-1\\\\=-5+5\cdot \:3-4+3\cdot \:10+15-\left(-9\right)-3-1\\\\=-5+15-4+30+15-\left(-9\right)-3-1\\\\=10-4+30+15-\left(-9\right)-3-1\\\\=51-\left(-9\right)-3-1\\\\=60-3-1\\\\=56$

Espero haberte ayudado
