(50*3-5)*2+100:(1+1)-40=300
50*3-(5*2+100):(1+1)-40=65
50(3+5*2)+100:(1+1)+40=750
50*3+5*2-100:(1+1)-40=60

Answer 1

(50*3-5)*2+100:(1+1)-40=300
50*3-5=145
2*145=290
100:2=50
50-40=10
290+10=300

Answer 2

(50×3-5)×2+100:(1+1)-40=300
(150-5)×2+100:2-40=300
145×2+50-40=300
         290+10=300
               300=300
