50+50+50x100-20
=50x3x100-20
=150x100-20
=15000-20
=14980
50 + 50 + 50 x 100 - 20 = 50 x 100 + 50 + 50 - 20 = 5000 + 50 + 50 - 20 =5100 - 20 = 5080
hoặc là 50 + 50 + 50 x 100 - 20 = 50 x 2 + 50 x 100 - 20 = 5100 - 20 = 5080
theo mk thì làm nhân trước cho đúng nha Nguyễn Linh Nhi
\(50+50+50\cdot100-20\\ =50\cdot2+50\cdot100-20\\ =100+5000-20\\ =5100-20=5080\)
50+50+50x100-20
=50+50+5000-20
=5100-20
=5080
50 + 50 + 50 x 100 - 20
= 50 x 3 x 100 -20
= 150 x 100 - 20
= 15000 - 20
= 14980
