1) 279 + 56 = 279 + (21 + 35) = (279 + 21) + 35 = 300 + 35 = 335
2) 313 + 88 = 313 + (87 + 1) = (313 + 87) + 1 = 400 + 1 = 401
3) 577 + 44 = 577 + (23 + 21) = (577 + 23) + 21 = 600 + 21 = 621
4) 94 + 628 = 94 + (622 + 6) = (94 + 6) + 622 = 100 + 622 = 722
5) 181 + 438 = 181 + (19 + 419) = (181 + 19) + 419 = 200 + 419 = 619
6) 166 + 255 = 166 + (34 + 221) = (166 + 34) + 221 = 200 + 221 = 421
7) 1205 + 796 = 796 + (204 + 1001) = (796 + 204) + 1001 =
= 1000 + 1001 = 2001
8) 2088 + 233 = 233 + (767 + 1321) = (233 + 767) + 1321 =
= 1000 + 1321 = 2321
