Question

Solve: 18[24 + (42 - 5 • 2)]

Answer 1

The given expression is

`18\lbrack24+(42-5\cdot2)\rbrack`

First, we solve the product

`18\lbrack24+(42-10)\rbrack`

Then, we solve the difference

`18\lbrack24+32\rbrack`

Now, we add

`18\lbrack56\rbrack`

At last, we solve the product

`18\lbrack56\rbrack=1008`

Hence, the answer is 1008.
