Question

ma puteti ajuta la exercitile 3 si 4?

Answer 1

3.  24-3x3=24-9=15
35+(35+19)=35+54=89
62-2x(9-1)=62-2x8=62-16=46 (! nu se vede prima cifra corect, am presupus ca e 62)
...x3+6x0=..x3+0=...x3 (nu se vede prima cifra)

4.  48:(4x2)=6   48:8=6
(6+3)x6=54     9x6=54
(56-6):5=10   50:5=10
5+(4x5):2=15   5+20:2=5+10=15
(72:8):3+3=6    9:3+3=3+3=6
83-(6x4):3=77   83-24:3=83-8=75 (probabil e o greseala)
