Bài 6: Tính bằng cách hợp lí

2008 + 2008 + 2008 + 2008 – 2008 x 4               

Answer 1

\(=4\times2008-2008\times4=0\)

Answer 2

\(2008+2008+2008+2008-2008\times4=2008\times4-2008\times4=0\)

Answer 3

2008 + 2008 + 2008 + 2008 - 2008 x 4

= ( 2008 x 4 ) - ( 200 x 4 )

= 0

Answer 4

2008 + 2008 + 2008 + 2008 – 2008 x 4    

⇔ (2008 x 4 ) - ( 2008 x 4 )

⇔ 0
