a) (-34) + (-91) + (-26) + (-99)
= [(-34) + (-26)] + [(-91) + (-99)]
= (-60) + (-190)
= - 250
a) ( - 34 ) + ( - 91 ) + ( - 26 ) + ( - 99 )
= [ ( - 34 ) + ( - 26 ) ] + [ ( - 91 ) + ( - 99 ) ]
= - 60 + ( - 190 )
= - 250
Cbht
\(a,\left(-34\right)+\left(-91\right)+\left(-26\right)+\left(-99\right)\)
\(=\left[\left(-34\right)+\left(-26\right)\right]+\left[\left(-91\right)+\left(-99\right)\right]\)
\(=\left(-60\right)+\left(-190\right)\)
\(=-250\)
