115- (-37)+2+(-49)+(-2)
= 115+37+2-49-2
= 152+2-49-2
= 105-2
=103
Tk mk nha
\(115-\left(-37\right)+2+\left(-49\right)+\left(-2\right)\)
\(=115+37+2-49-2\)
\(=152-49\)
\(=103\)
115 - ( - 37 ) + 2 + ( - 49 ) + ( - 2 )
= 115 - [ ( - 37 ) + ( - 49 ) ] + [ 2 + ( - 2 ) ]
= 115 - ( - 86 ) + 0
= 115 + 86
= 201
115-(-37)+2+(-49)+(-2)
=152+2+(-49)+(-2)
=154+(-49)+(-2)
=205
