Answer 1

Explicație pas cu pas:

a) 125-31+9:9-4×3+16:4×5=

125-31+1-12+4×5=

92-11+20=

81+20=91

b) 5×1000-816+12×3:1-56+4×8=

5000-816+36-56+32=

4184-20+32=4196

c) (36:9×4:2+51)+(100-81:9×2)+5=

(4×2+51)+(100-9×2)+5=

59+82+5=146

d) 4808-(50:5×31+6)+3×(200×3-48+47-499)=

4808-(10×31+6)+3×(600-48-452)=

4808-316+3×100=

4492+300=4792

e) 6+(6+6×6-6:6-1×6)-6×(6:6+6×6:6×0)=

6+(6+36-1-6)-6×(1+6×1×0)=

6+35-6×1=

6+35-6=35
