Răspuns:

Explicație pas cu pas:

1. 2-(-3-2)-(-5 – 3) =2-(-5)-(-8) =2+5+8 =15
2. -2.(-5+8-9) =-2x(3+9) =-2x12 =-24
3. (15–27):(8-4) =-12:4 =-3
4. (18:6–27): (12:4-11) =(3-27):(3-11) =-24:(-8) =3
5. (-48):(-6)+9.(-3 - 2) =8+9x(-5) =8+(-45) =-37
6. 15+(-5+7)-(-9+3) =15+2-(-6) =17+6 =23
7. (-24):(7-12 +6-5) =-24:6 =-4
8. (-1-2).(9-16) =-3x(-7) =21
9. 2.(-3)-5.(7-17) =-6-5x(-10) =-6+50 =44
10. 2010:(-36-2 -15:3) =2010:(-38-5) =2010:(-43) =-2010/43 =-46$\frac{32}{43\\}$
