Question

1) [(-8) + {78 + 133] • (-5)

Answer 1

We have the following expression:

`\left\lbrack (-8)+\left\lbrace 78+133\right\rbrace \right\rbrack \cdot(-5)`

We can start solving the sum and we have:

`\left\lbrack -8+(211)\rbrack\cdot(-5\right)`

Then we can solve the operation inside the [] and we got:

`\left\lbrack 203\rbrack\cdot(-5)=-1015\right?`

And the final answer would be -1015
