Answer 1

Răspuns

Explicație pas cu pas:

a)   10 x 300 : 10 - 181 000 : 1 000 = 119

= 3 000 : 10 - 181 =

= 300 - 181 =

= 119

b)   ( 963 + 37 ) : 1 000 + 1 000 x 77 = 77 001

= 1 000 : 1 000 + 77 000 =

= 1 + 77 000 =

= 77 001

c)   1 000 000 : 10 : 100 : 1 000 + 29 999 = 30 000

= 1 + 29 999 =

= 30 000

d)   ( 299 999 + 1 ) : 1000 : 10 : 10 = 3

= 300 000 : 1 000 : 10 : 10 =

= 300 : 10 : 10 =

= 30 : 10

= 3

Explicație pas cu pas:

a) 3000:10  -  181 = 300 - 181 = 119

b) 1000:1000  +  1000x77 =

1+ 77000 =

77001

c) 10^6 : 10^(1+2+3)  + 29999 =

10^(6-6) + 29999 =

10^0 + 29999 =

1 + 29999 =

30000.

d) 300000 : 100000 = 3
