a,258-(122-(-358+322))
=258-(122+358-322)
=258-122-358+322
=(258-358)+(-122+322)
=-100+200=100
k cho tớ nhé ^^Tớ giải tiếp cho
Trả lời:
\(a,\)\(258-\left[122-\left(-358+322\right)\right]\)
\(=258-\left(122+358-322\right)\)
\(=258-122-358+322\)
\(=\left(258-358\right)-\left(122-322\right)\)
\(=\left(-100\right)-\left(-200\right)\)
\(=-100+200\)
\(=100\)
