Question

1) Efectueaza cu atentie calculele :. a)1000 + 1000 × 10 - 10 × 100 + 100 × 10 × 0 = b) 10× 10 × 10 + 100 × 100 × 100 - 1000 × 1000 = c) 700542 - 838 × 100 - ( 990 + 3 - 1000) : 5 =

Answer 1

a)1000 + 1000 × 10 - 10 × 100 + 100 × 10 × 0=
1000+10000-1000+0=
11000-1000=
=10 000

b) 10× 10 × 10 + 100 × 100 × 100 - 1000 × 1000 =
=1000 +1 000 000 -1 000 000
= 1000

c) 700542 - 838 ×100 - ( 990 + 3 - 1000) : 5 =
=700542 - 838 x 100 + 7 :5
=700542 - 83800 + 1,4
=616743,4

Sper sa fie corect! Imi pare rau daca am gresit la un calcul!
