g)[(126x4+76x6):5]+[(280+120):4]x2

Answer 1

a)118:2=59
b)162+438:6=162-73=89

c)970-(208x4-507)=
 970-325=645

d)[990-(279+132)]:3=
  (990-441):3=
579:3193

e)(165x2):5=
330:5=66

f){707-384+(142+212):2]:4x7
(707-384+354:2):4x7=
(323+177):4x7=
500:4x7=
125x7=875

g)(504+456):5+(400:4)x2=
960:5+10x2=
192+20=212
