Question

a=3×3+2×4×(7+6×(2×10÷3)÷2×1)÷1000÷10 b=9+(7+3×(12÷7)÷2÷5×2​

Answer 1

a=3×3+2×4×(7+6×(2×10÷3)÷2×1)÷1000÷10

9+8(7+6*60/9:2):1000:10

9+8(7+360/9:2):1000:10

9+8(7+40:2):1000:10

9+8(7+20):1000:10

9+216:1000:10

9+0,216:10

9,0216

b=9+(7+3×(12÷7)÷2÷5×2

9+(7+3*12/7:3:5*2)

9+(7+36/7:3:5*2)

9+(7+12/7:5*2)

9+(7+2,4/7*2)

9+(7+4,8/7)

9+53,8/7

116,8/7
