Answer 2

Explicație pas cu pas:

140+25:(13-56:7)+8=153

140+25:(13-8)+8=153

140+25:5+8=153

140+5+8=153

145+8=153

153=153 (A)

200-(5x8+25x2)-42:6=203

200-(40+50)-7=203

200-90-7=203

110-7=203

103=203 (F)

85+25:(14-81:9)+912=219

85+25:(14-9)+912=219

85+25:5+912=219

85+5+912=219

90+912=219

1002=219 (F)
