Explicație pas cu pas:
a) 2+3+97+98= 200
= (2+98) + (3+97) =
= 100 + 100 =
= 200

b) 5+13+19+87+95+1= 220
= ( 95 + 5) + (13+87) + (19+1) =
= 100 + 100 + 20 =
= 220

c) 16+184+982+118+66+134= 1 500
= (16+184) + (982+118) + (66+134) =
= 200 + 1 100 + 200 =
= 1 500

d) 355+129+678+645+322+871= 3 000
= (355+645) + (129+871) + (678+322) =
= 1 000 + 1 000 + 1 000 =
= 3 000
