Question

Find the value of: $373+(-245)+(-373)+145+3000$

Answer 1

Simplification of integers:

$\begin{array}{rcl}373+(-245)+(-373)+145+3000& =& \left\{373+(-373)\right\}+(-245)+145+3000(\mathrm{Associative}\mathrm{Property})\\ & =& 0+(-245)+145+3000\\ & =& \left\{-245+145\right\}+3000(\mathrm{Plus}\mathrm{and}\mathrm{minus}\mathrm{is}\mathrm{minus}\mathrm{and}\mathrm{sign}\mathrm{of}\mathrm{the}\mathrm{greater}\mathrm{number}\mathrm{comes})\\ & =& -100+3000\\ & =& 2900\end{array}$

Hence, $373+(-245)+(-373)+145+3000=$ $2900$
