2. Розв’яжи, міркуючи за зразком
340 + 440 = (300 + 400) + (40 + 40) =__________________
660 + 320 = (600 + 300) + (60 + 20) = __________________
470 + 120 = (400 + 100) + (70 + 20) = __________________
250 + 430 = (200 + ___) + (_______) =_________________
560 + 330 = (500 + ___) + (_______) = ________________
470 + 320 = (400 + ___) + (_______) = _________________
610 + 380 = ______________________________________
270 + 720 = ______________________________________
