123.456+456.123-256.444
= 456.(123+123) - 256.444
=456.246 - 256.444
=112176-113664
=-1488
123.456+456.123-256.444
=123.(456+456)-113664
=123.912-113664
=112176-113664
= -1488
\(123\times456+123\times456+256-444\)
\(=123\times\left(456+456\right)+113664\)
\(=123\times912-113664\)
\(=112176-113664\)
\(=-1488\)
_Chúc bạn học tốt_
Trả lời:
\(123.456+456\cdot123-256\cdot444\)
\(=123\cdot\left(456+456\right)-113664\)
\(=123\cdot912-113664\)
\(=112176-113664\)
\(=-1488\)
