Question

Answer 1

\(a,14-\left(-5\right)-21=14+5-21=-2\\ b,\left(-27\right)+16-19=-11-19=-30\\ c,12-\left(10-19\right)=12-\left(-9\right)=12+9=21\\ d,\left(-27\right)-\left(13-19\right)=\left(-27\right)-\left(-6\right)=-27+6=-21\)

Answer 2

a,14−(−5)−21=14+5−21=−2b,(−27)+16−19=−11−19=−30c,12−(10−19)=12−(−9)=12+9=21d,(−27)−(13−19)=(−27)−(−6)=−27+6=−21
