Answer 1

1.

a)28-5:4=

23:4=5,75

50:20•7=

2,5•7=17,5

b)36+21:7+15=

36+3+15=

39+15=54

64-35:5-32=

64-7-32=

57-32=25

c) (24-12:2•0)+(7•8-8•4)=

(24-6•0)+(56-8•4)=

(24-0)+(56-32)=

24+(56-32)=

24+24=48

(64:8+2):(36:6+4)=

(8+2):(6+4)=

10:(6+4)=

10:10=1

d) (24:4)+(10•5)+(100•0)=

6+(10•5)+(100•0)=

6+50+(100•0)=

6+50+0=

56+0=56

95-6•8+20=

95-48+20=

43+20=73

8•25+9•36=

200+9•36=

200+324=524

2.

3•6+3=

18+3=21

3•(6+3)=

3•9=27

10•5-2=

50-2=48

10•(5-2)

10•3=30

21:3+4=

7+4=11

21:(3+4)=

21:7=3

Noi observam ca o singură pereche de paranteze poate schimba totul .Adică toata ecuația sau tot calculul.
