\(a,126+\left(-10\right)+\left(-100\right)+\left(-126\right)\)
\(=\left[\left(126+\left(-126\right)\right)\right]+\left[\left(-10\right)+\left(-100\right)\right]\)
\(=0+\left(-110\right)\)
\(=-110\)

\(b,\left(-213\right)+89+13+11\)
\(=\left[\left(-213\right)+13\right]+\left(89+11\right)\)
\(=-200+100\)
\(=-100\)
