Am facut bine daca nu am facut spuneti-mi voi cum scriu..

Answer 1

1) 4560+1320+1440+2680 = (4560+1440) + (1320+2680) =

6000+4000 = 10000

2) 2890+2350+1110+2650 =(2890+11110)+(2350+2650) = 4000+5000 = 9000

3) 2345+3540+1460+1655 =(2345+1655)+(3540+1460) = 4000+5000 = 9000

4) 3450+550+650+3350 = (3450+550)+(650+3350) = 4000+4000=8000
