ko vt lại đề

mà cái này bấm máy tính là ra.........

\(126+\left(-20\right)+|124|-\left(-320\right)-|-150|\)

\(=126-20+124+320-150\)

\(=400\)

= 126 + ( - 20 ) + 124 - ( - 320 ) - 150

= ( 126 + ( - 20 ) ) + 124 - ( - 320 ) - 150

= 106 + 124 - ( - 320 ) - 150

=( 106 + 124 ) - ( - 320 ) -150

= 230 - ( - 320 ) - 150

= ( 230 - ( - 320 ) ) -150

= 550 - 150

= 400 

\(=100+124+320-150\)

\(=224+320-150\)

\(=544-150\)

\(=394\)

=106+124-320-150

=230-170

=60

=126 + (-20) + 124 - (-320) - 15

= 106 + 124 - (-320) - 15

=   230 - (-320) -15

=  230 + 320 - 15

=  550 - 15

=   535

126+(-20)+|124|-(-320)-|-150|

=400

73 . 35 + 27 . 19 - 20 . 73 + 81 . 27 + 85 . 73
