Answer 1

Answer:

(i) (-5)+(-8)=(-8)+(-5)

(-5)-8=(-8)-5

-13=-13

(ii)-53+0=-53

when 0 is added to any number, the answer will be the number itself

(i) 17+(-17)=0

17-17=0

(ii)[13+(12)]+(-7)=13+[(-12)+(-7)]

[13+12](-7)=13-12-7

(25)(-7)=13-12-7

25-7=13-12-7

18=1-7

18=6

therefore these numbers are not equal to each other

(iii) (-4)+[15+(-3)]=[-4+15]+(-3)

(-4)+[15-3] =(12)-3

(-4)+12=9

8=9

therefore they are not equal to each othr
