VA ROG DAU 100 PUNCTE: (1)calculati suma nr a si b unde: a=305.7 -105 .27 si b= 19.2 - 17.02 +137.34 (2)calculati diferenta numerelor a si b unde a=3.125 +15+82.3-17.32 si b=13.7 -1.05 +21.31​

Răspuns :

1)a=305,7-105,27

a=200,43

b=19,2-17,02

b=2,18

a+b=200,43+2,18

a+b=202,61

2) a=3,125+15+82,3-17,32

a=18,125+82,3-17,32

a=100,425-17,32

a=83,105

b=13,7-1,05+21,31

b=12,65+21,31

b=33,96

a-b=83,105-33,96

a-b=49,145
