Question

Let a,b,c be the three rational numbers , where a=23,b=45and c=56 verify: a+(b+c) = (a+b)+c​

Answer 1

Answer:

$a=23,b=45, c=56$

To verify:  a+(b+c)= (a+b)+c

$LHS: a+(b+c)$

        $=23+(45+56)$

        $=23+101$

        $=124$

$RHS: a+(b+c)$

        $=(23+45)+56$

        $=68+56$

        $=124$

$LHS=RHS$

Hence, Proved
