15 - 36:(3 x 3 x 3:3 +0:5) + 30 :(3:3+5) =

rezolvam parantezele

3 x 3 x 3:3 +0:5=9+0=9

3:3+5=1+5=6

15-36:9+30:6=15-4+5=16

a=16

25+[7×2×18:2-5x(5x4-36:3)]=

rezolvam paranteza rotunda

5x4-36:3=20-12=8

25+[7×2×18:2-5x8]=

rezolvam paranteza pătrată

7×2×18:2-5x8=14×9-40=126-40=86

b=86

Răspuns:

A=15-36:9+30:6

A=15-4+5

A=11+5

A=16

B=25+[14×9-5×(20-12)]

B=25+(126-5×8)

B=25+(126-40)

B=25+86

B=111
