Question

выполните сложение "цепочкой" по образцу:
45+5+17+20=50+17+20=67+20=87
8+9+13+22; 37+33+19+3; 4+6+19+21; 38+2+5+28; 3+6+35+16; 513+2+15+17; 5+25+8+101; 164+6+9+12.

Answer 1

45 + 5 + 17 + 20 = 50 + 17 + 20 = 67 + 20 = 87

8 + 9 + 13 + 22 = 17 + 13 + 22 = 30 + 22 = 52

37 + 33 + 19 + 3 = 70 + 19 + 3 = 89 + 3 = 92

4 + 6 + 19 + 21 = 10 + 19 + 21 = 29 + 21 = 50

38 + 2 + 5 + 28 = 40 + 5 + 28 = 45 + 28 = 73

3 + 6 + 35 + 16 = 9 + 35 + 16 = 44 + 16 = 60

513 + 2 + 15 + 17 = 515 + 15 + 17 = 530 + 17 = 547

5 + 25+ 8 + 101 =  30 + 8 + 101 = 38 + 101 = 139

164 + 6 + 9 + 12 = 170 + 9 + 12 = 179 + 12 = 191
