Question

120÷1+10×5=
120÷20+12×5=
120÷30+6×5=
120÷40+6×5=
120÷12+0×5=

Answer 1

120÷1+10×5= 170 
1) 120 : 1 = 120
2) 10 * 5 = 50
3) 120 + 50 = 170 

120÷20+12×5= 66
1) 120 : 20 = 6
2) 12 * 5 = 60
3)6 + 60 = 66


120÷30+6×5= 34
1) 120 :30 = 4
2) 6 * 5 = 30 
3) 4 + 30 = 34


120÷40+6×5= 33
1) 120 : 40 = 3
2) 6 * 5 = 30
3) 3 + 30 = 33


120÷12+0×5= 10
1) 120 : 12 = 10
2) 0 * 5 = 0
3) 10 + 0 =10

Answer 2

120:1+10•5=120+50=170
120:20+12•5=6+60=66
120:30+6•5=4+30=34
120:40+6•5=3+30=33
120:12+0•5=10+0=10
