8. Vrei o notă bună? Calculează:
a) 4-(3,19-2) =
c) 8.13 - (10-0,78 -2,9) =
e) 5-[4,12 – (4,18 -3,9)] =
g) 15- (7,18 +6,78) =
i) 18-(2,8+(3,9+8-5,17)]=
k) 13,68 - [4,81 – (5,19-3,87-1)]=
b) 5,107 -(5-0,14) =
d) (4-3,8) - (5-4,6-0,25) =
f) 6,102-(4,921 +1,001) =
h) 5,13-(4,98 -2,106)-(5-3.17) =
j) 5,65-(3,8+1,92-2) =
1) 23-(59,41 - 42,107)-(7-5,12)= va rog urgent dau coroana!​
