Question

can i get q 8 and Q9 answer step by step

Answer 1

Q8)

1) <

2) <

3) >

Q9) a-(-b)=a+b [I'm taking it as a-(-b) because I think the question may be wrong cause a-(b) is not equal to a+b]

1) a= 12 b= 18

a- (-b) = a + b

12-(-18)=12+18

12+18=12+18

30=30

2) a=21 b=10

a-(-b)=a+b

21-(-10)=21+10

21+10=21+10

31=31
