Simplify $ \{-13-(-27)\}+\{-25-(-40)\} $.
Given:
\( \{-13-(-27)\}+\{-25-(-40)\} \).
To do:
We have to simplify \( \{-13-(-27)\}+\{-25-(-40)\} \).
Solution:
We know that,
$[(-)\times(-)=(+)]$
Therefore,
$[-13-(-27)]+[-25-(-40)]=[-13+27]+[-25+40]$
$=(14)+(15)$
$=29$
${-13-(-27)}+{-25-(-40)}={-13+27}+{-25+40}=29$.
