Răspunsuri:

a) 7+3*[23+5*(8+66:6)]=

=7+3*[23+5*(8+11)=

=7+3*(23+5*19)=

=7+3*(23+95)=

=7+3*118=

=7+354=

=361

b)91+56:2+33*(156-12*13)=

=91+28+33*(156-156)=

=91+28+33*0=

=91+27+0=

=118

c) [200-200:(75-25)]:4=

=(200-200:50):4=

=(200-4):4=

=196:4=

=49

d) 1000*[105:5+32:(22-6*3)]=

=1000*[21+32:(22-18)=

=1000*(21+32:4)=

=1000*(21+8)=

=1000*29=

=29000

e) (1+2+3)^4+5*6*(7+8+9)=

=6^4+30*24=

=6^4+720=

=1296+720=

=2016

f) 0^1+1^0+2^3-3^2+4^5+5^4-349=

=0+1+8-9+1024+625-349=

=9-9+1023+625-349=

=0+1023+625-349=

=1023+625-348=

=1648-348=

=1300
