Answer 2

Răspuns:

a) 3628-(314+2×5-39)×7=

=3628-(314+10-39)×7

=3628-(354-39)×7

=3628-315×7

=3628-2205

=1423

b) 990+6+0×345+1:1=

=990+6+0+1

=990+7

=997

c) 42×20×2540-32:4=

=840×2540-8

=2133600-8

=2133592

d) 36-18:2:(3×3)+240=

=36-9:9+240

=36-1+240

=35+240

=275

e) (743-697)×18+5×9:5=

=46×18+5×9:5

=828+40:5

=828+9

=837

f) 54+25:5×(349-187)=

=54+25:5×162

=54+5×162

=54+810

=864

g) 6000-82×13+(25-20):5

=6000-82×13+5:5

=6000-82×13+1

=6000-1066+1

=6000-1067

=4933
