Răspuns:

f) 15.000-250:5+15:5+[265-(2+2)×65]=

=15000-250:5+15:5+[265-4×65]=

=15000-250:5+15:5+[265-260]=

=15000-250:5+15:5+5=

=15000-50+15:5+5=

=15000-50+3+5=

=14950+3+5=

=14953+5=

=14958

g) 280.026-89.275-441-(149-100):7=

=280.026-89.275-441-49:7=

=280.026-89.275-441-7=

=190.751-441-7=

=190.310-7=

=190.303

j){[180-7×(264-253+3)]-[55:9]}:2=

={[180-7×(11+3)]}-6,1:2=

={[173×14]}-3,05=

=2422-3,05=

=2418,95
