Răspuns:
a) (42+3):3+(52×3)×0 = 15
b) 2×[125-60:(9-3)]-2 = 228
c) 25+[(36:6:2)+12×3] = 64
Explicație pas cu pas:
a)
(42+3):3+(52×3)×0=
= 45:3+156×0
= 15+0
= 15
b)
2×[125-60:(9-3)]-2=
= 2×(125-60:6)-2
= 2×(125-10)-2
= 2×115-2
= 230-2
= 228
c)
25+[(36:6:2)+12×3]=
= 25+[(6:2)+12×3]
= 25+(3+12×3)
= 25+(3+36)
= 25+39
= 64
