Hej!
Od a) do c) :
[tex]a] \ (-2+5)\cdot(-3)=3\cdot(-3)=\boxed{-9}\\\\b] \ (-3-8)\cdot(8-12)=-11\cdot(-4)=\boxed{44}\\\\c] \ \frac{(4-(-6))}{-2}=\frac{4+6}{-2}=\frac{10}{-2}=\boxed{-5}[/tex]
Od d) do f) :
[tex]d] \ (-13-8):(-3+10)=-21:7=\boxed{-3}\\\\e] \ (-3)\cdot(2-7)-(-6+2)=(-3)\cdot(-5)-(-4)=15+4=\boxed{19}\\\\f] \ \frac{(12-18)-(17-(-3))}{10-15}=\frac{-6-(17+3)}{-5}=\frac{-6-20}{-5}=\frac{-26}{-5}=\boxed{5,2}[/tex]
