1. (-12-(-6))÷(8+(-10)) 2. (20-(-5)×(-14-(-10)) 3. {[(40:5)×6]-19)×3 4. [42÷(4+3)]×[63-(11×4)] 5. {[(25÷5)-8]×5}-41 tolong yaa.... Anda yang terbaik

1. (-12-(-6):(8+(-10)= (-12+6):(8-10)=-6÷-2=3 <--
2.(20-(-5)×(-14-(-10)=(20+5)×(-14+10)=25×-4=-100 <--
3.{[(40÷5)×6]-19}×3={[8×6]-19}×3={14-19}×3=-5×3=-15 <--
4.[42:(4+3)]×[63-(11×4)]=[42:7]×[63-44]=6×19=114
5.{[(25÷5)-8]×5}-41={[5-8]×5}-41={-3×5}-41=-15-41=-56
