1b. zero 0

1 c 18:3=6 6×3=18

1d. 6×6

Answer 2

Răspuns:

1a. B.8

1b. 36

1c. 2

1d. 14

2. 7×8:2*2+18:3×2-2*0

7×8:4+18:3×2-1

56:4+18:3×2-1

14+18:3×2-1

14+6×2-1

14+12-1

26-1

RASPUNS : 25

3. C.96

4.{8+2×[9+9×(7+2×3)]} ×2-4×23

{8+2×[9+9×(7+6)]} ×2-4×23

[8+2×(9+9×13)] ×2-4×23

[8+2×(9+117)] ×2-4×23

(8+2×126)×2-4×23

(8+252) ×2-4×23

260 ×2-4×23

520-4×23

520-92

RASPUNS : 428

5. Aici nu stiu

6. 5 creioane => 5 × 2 = 10 lei

4 pixuri => 4 × 3 = 12 lei

10+12= 22 lei 3 bancnote 10 lei

3×10 = 30 lei

30 - 22

RASPUNS : 8 LEI

7. a) Fals 18 : 6 - 3 = (facem prima data împărțirea )

3-3 = 0

b)Fals (1+2*3)×3+1 = (aflam prima data puterea)

(1+8)×3+1

8×3+1

24+1= 25

8. x=(3×5^2+1)-[(2+3×5^2):11+1]

x=(3×25+1)-[(2+3×25):11+1]

x=(75+1)-[(2+75):11+1]

x=76-(77:11+1)

x=76-(7+1)

x=76-8

x=68

9. Nu sunt sigura dar cred ca e asa => [(25+250):(5-4)]×6

SPER CA TE-AM AJUTAT!!! COROANA ???? CHIAR AM MUNCIT MULT
