Answer:
(i)LHS=a−(−b)
=21−(−18)
=−[−21−18]=+39
RHS=21+18=39
∴LHS=RHS
(ii)LHS=a−(−b)
=75−(−10)
=−[−75−10]
=85
RHS=75+10=85
∴LHS=RHS

Given: a=1 /2 b=1/3
To verify a+b=b+a and a×b=b×a
Solution:
2. a +b=b+a
1/2+1/3=1/3+1/2
3+2/6=2+3/6
5/6=5/6
hence proved
1.a×b=b×a
1/2×1/3=1/3×1/2
1/6 =1/6
hence proved
conclusion: we can say that addition and multiplication obeys the commutative law
