Answer 1

42 - 15 + 35 = 42 + 20 = 62
50*5 - 90 + 520:20 = 250 - 90 + 26 = 160 + 26 = 186
270:(70:5+16)*2= 270:(14 + 16)*2 = 270:30*2 = 9*2 = 18
29*10:5= 290:5 = 58
1800:2-18*5+45:5= 900 - 90 + 9 = 810 + 9 = 819
(60:12+45)-(14*2+12)= (4+45)-(28+12) = 50-40 = 10
57+4*12-15= 57 +48 - 15 = 42 + 48 = 90
450-270+20*4= 180 + 80 = 260
58-(26+13)= 58 - (39) = 19

Answer 2

1. 42 - 15 + 35 = 27 + 35 = 62
2. 50 * 5 - 90 + 520 : 20 = 250 - 90 + 26 = 186
3. 270 : (70 : 5 + 16) * 2 = 270 : (14 + 16) * 2 = 270 : 30 * 2 = 270 : 60 = 4.5
4. 29 * 10 : 5 = 290 : 5 = 58
5. 1800 : 2 - 18 * 5 + 45 : 5 = 900 - 90 + 9 = 819
6. (60 : 12 + 45) - (14 * 2 + 12) = (5 + 45) - (28 + 12) = 50 - 40 = 10
7. 58 - (26 + 13) = 58 - 39 = 19
