Answer 1

c) 22-{22-[20-(40-22)+(88-22)-(88-40)]}=22-[22-(20-18+66-46)]=22-[22-(2+18)]=22-(22-20)=22-2=20 f) 1-{2+(3-4)-[6-(7-8)+(9-10)]-11}+12=1-{2+(-1)-[6-(-1)+(-1)]-11}+12=1-[2-1-(6+1-1)]-11}+12=1-[1-(7-1)]-11}+12=1-[(1-6)-11]+12=1-(-5-11)+12=1-(-16)+12=1+16+12=17+12=29 Ti-l rezolv si pe a) doar sa imi spui unde se inchide paranteza patrata
