We know that `3+5=5+3=8` that is the whole numbers can be added in any order . In other words , addition is commutative for whole numbers
Can we say the same fot integers also ? We have `5+(-6)=(-6)+5`
Are the following equal ?
(i) `(-8)+(-9)and(-9)+(-8)`
(ii) `(-23)+32and32+(-23)`
(iii) `(-45)+0and0+(-45)`
Try this with five other pairs of inegers .Do you find any pairs of intergers for which the sums are different when the order is changed ?
