a= 50+9:9-45 => a= 50+1-45 => a= 51-45 => a= 6
b= 3×(300-55×5)×2+3-(14:7-5×0) => b= 3×(300-275)×2-3-(2-0) => b= 3×25×2+3-2 => b= 75×2+1 => b= 150+1 => b= 151
c= 35×2+45×3 => c= 70+135 => c= 205

6×151-205= 906-205= 701

a= 50+9:9-45=50+1-45= 6
b= 3x(300-55x5)x2 +3-(14:7-5x0) = 3x(300-275)x2+3- 2= 3x50 +1=151
c= 35x2+45x3= 70+135=205
6x151-205=906-205=701
