Thực hiện phép tính (tính hợp lí nếu có thể): ( − 3 ) + 350 + ( − 350 ) + ( − 7 )

\[\left( { - 3} \right) + 350 + \left( { - 350} \right) + \left( { - 7} \right)\]

\[ = \,\,\,\left[ {\left( { - 3} \right) + \left( { - 7} \right)} \right] + \left[ {350 + ( - 350)} \right]\]

\[ = \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 10\,\,\,\,\,\,\,\,\,\,\, + \,\,\,\,\,\,\,0\]

\[ = \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 1\,0\]
