Question

Afla x+y+z,știind ca:x=9•6-81:9+(32-12:2);y=10•10•10:10+(45-42:6);z=70-(16+16:8)

Answer 1

Răspuns:

x=

1)32-12:2=26

2)9×6=54

3)81:9=9

4)54-9+26

x=71

y=

1)42:6=7

2)45-7=38

3)10×10×10=1000

4)1000:10=100

5)100+38=138

y=138

z=

1)16:8=2

2)16+2=18

3)70-18=52

z=52

Explicație pas cu pas:

x+y+z=

71+138+52=261
