Question

-23-24-25+123+124+125 tính hợp lí

Answer 1

\(-23-24-25+123+124+125\\ =\left(123-23\right)+\left(124-24\right)+\left(125-25\right)\\ =100+100+100\\ =300\)

Answer 2

=(-23+123)+(-24+124)+(-25+125)

=100+100+100

=300

Answer 3

=300

Answer 4

−23−24−25+123+124+125

=(123−23)+(124−24)+(125−25)

=100+100+100

=300
