Answer 1

a) -4+(-3)÷[2-(-6)÷(-2)]+1=
= -4-3÷(2-3)+1=
= -4-3÷1+1=
= -4-3+1= -6

b) 3-2×{5-3×[4-(-2)÷(-1)]}=
= 3-2×[5-3×(4-2)]=
= 3-2×(5-3×2)=
= 3-2×(5-6)=
= 3-2×(-1)=
= 3+2=5


c) -2×[3-(-6)pătrat ÷(-9)]-2×[5-(-7)]=
= -2×(3-36÷(-9)-2×12=
= -2×(3+4)-24=
= -2×7-24=
= -14-24= -34

d) -5 pătrat +3÷[7-(-4)÷(-1)]=
= -25+3÷(7-4)=
= -25+3÷3=
= -25+1= -24

e) (-2) cub-2 pătrat -(-6)×(7-8)=
= -8-4+6×(-1)=
= -8-4-6= -18

f) 5×[2 cub +(-7)×2-(1-6)]=
= 5×(8-14+5)=
= 5×(-1)= -5

g) (2-5) cub -2 cub +5 cub=
= 2 cub - 5cub - 2 cub + 5 cub=
=0

h) (-2) cub ×(-4)-3 pătrat ×[2-3×(-4+6)]=
= -8×(-4)-9×(2-3×2)=
= 32-9×(2-6)=
= 32-9×(-4)=
= 32+36= 68

i) -(-3)-|2-7|÷(|-2| - |-7|)=
= 3-|-5|÷(2-7)=
= 3-5÷(-5)=
= 3+1= 4

j) -(+4)-|12-8|÷(|-2+5|-|-1|)=
= -4-|4|÷(|3|-1)=
= -4-4÷2=
= -4-2= -6
