1)279+56= 279 + (21 + 35) = (279 + 21) + 35 = 300 + 35 = 335

3)577+44= 577 + (23 + 21) = (577 + 23) + 21 = 600 + 21 = 621

5)181+438= (119 + 62) + 438 = 119 + (62 + 438) = 119 + 500 = 619

7)1205+796= 1205 + (95 + 701) = (1205 + 95) + 701 = 1300 + 701 = 2001

2)313+88= (301 + 12) + 88 = 301 + (12 + 88) = 301 + 100 = 401

4)94+628= 94 + (622 + 6) = (94 + 6) + 622 = 100 + 622 = 722

6)166+255= 166 + (221 + 34) = (166 + 34) + 221 = 200 + 221 = 421

8)2088+233= 2088 + (221 + 12) = (2088 + 12) + 221 = 2100 + 221 = 2321
