Question

Find the answer of the following addition: $(-11)+(-12)$.

Answer 1

Finding the value of given expression.

$\begin{array}{rcl}(-11)+(-12)& =& -11-12\end{array}$ (open the brackets and multiplication of $+$ sign with $-$ sign is $-$)

$=-23$ (To add two $-$ numbers, add the numbers and put $-$ sign)

Hence, $(-11)+(-12)=-23$.
