Răspuns :

3624+4532=
(3000+600+20+4) + (4000+500+30+2)=
(3000+4000) + (600+500) + (20+30) + (4+2)=
7000 + 1100 + 50 + 6 =
8156

3 624 + 4 532 =8 156

= ( 3 000 + 600 + 20 + 4 ) + ( 4 000 + 500 + 30 + 2 ) =

= ( 3 000 + 4 000 ) + ( 600 + 500 ) + ( 20 + 30 ) + ( 4 + 2 ) =

= 7 000 + 1 100 + 50 + 6 =

= 8 156
