Question

Tính giá trị biểu thức:

12 000 - (1500 . 2 + 1800 . 3 + 1800 . 2 : 3).

Answer 1

12 000 - (1500 . 2 + 1800 . 3 + 1800 . 2 : 3)

= 12 000 - (3000 + 5400 + 3600 : 3)

= 12 000 - (3000 + 5400 + 1200)

= 12 000 - 9600 = 2400.

 

Answer 2

\(12000-\left(1500.2+1800.3+1800.2:3\right)\)

\(=12000-\left(3000+5400+3600:3\right)\)

\(=12000-\left(3000+5400+1200\right)\)

\(=12000-\left(8400+1200\right)\)

\(=12000-9600\)

\(=2400\)
