Question

$\left(-57\right)\times \left(-19\right)+57=$

Answer 1

Solve the given expression.

According to BODMAS rule, first solve the multiplication and then the addition.

$\begin{array}{rcl}\left(-57\right)\times \left(-19\right)+57& =& \left(57\times 19\right)+57\left[\because \left(-\mathrm{sign}\right)\times \left(-\mathrm{sign}\right)=\left(+\mathrm{sign}\right)\right]\\ & =& 1083+57\\ & =& 1140\end{array}$

Hence, the required value of expression is $\left(-57\right)\times \left(-19\right)+57=1140$.
