Question

(Q )Verify [ x+y] < [x] +[ Y] in the following. (1) x = –1,y = –16/5 .​

Answer 1

Firstly considering LHS

[x+y] = [-1 + (-16/5)]

= [-1 -16/5]

= [-5-16/5]

= [-21/5]

Now considering RHS

[x] + [y] = [-1] + [-16/5]

= [-1 -16/5]

= [-5-16/5]

= [-21/5]

here we see both LHS and RHS are equal,

the question [x+y] < [x] + [y] is False.
