Question

tính nhanh nếu có thể:

12000-(1500.2+1800.3+1800.2:3)

Answer 1

   12 000 - ( 1 500 x 2 + 1 800 x 3 + 1 800 x 2 : 3 )

= 12 000 - ( 3 000 + 5 400 + 1 200 )

= 12 000 - 9 600

= 2 400

Answer 2

   12 000 - ( 1 500 x 2 + 1 800 x 3 + 1 800 x 2 : 3 )

= 12 000 - ( 3 000 + 5 400 + 1 200 )

= 12 000 - 9 600

= 2 400

Answer 3

12000-(1500x2+1800x3+1800x2:3)

=12000-(3000+5400+1200)

=12000-9600

=2400
