Calculează:
a) 1 000 - 409 x 6:3 + 56 : 8 x 5 =
b) 234 + [( 88:4+ 16) - 78:6] x 23 =
c) 100 - {62 - 3 x[ 12:(5:5+ 3) +48:4-1]} x 5+1 =​

Answer 1

Răspuns:

a)1000-2254 : 3+56 : 40=

1000-751,3 + 1,4=

1000-752,7=

=247,3

b)234+[(22 +16)-78:6] × 23=

234 +(38-13)×23=

234+ 25×23=

234+575=

=809

Answer 2

Răspuns:

a) 1 000-2.454:3+7×5=

1.000-818+35=

182+35=217

b)234+[(22+16)-78:6]×23=

234+(38-13)×23=

234+25×23=

234+575=809

c)100-{62-3×[12:(1+3)+48:4-1]}×5+1=

100-[62-3×(12:4+48:4-1)]×5+1=

100-[62-3×(3+12-1)]×5+1=

100-[62-3×(15-1)]×5+1=

100-(62-3×14)×5+1=

100-(62-42)×5+1=

100-20×5+1=

100-100+1=

0+1=1
