Re: [Chicken-users] Why doesnot "(+ 1/2 1/3)" equal to 5/6 ?

[z_axis]

Welcome to Racket v5.3.
-> (+ 1/2 1/3)
5/6

BTW, what do the following message mean ?
(use numbers)
; loading /usr/local/lib/chicken/6/numbers.import.so ...

Note: re-importing already imported identifier: +

Note: re-importing already imported identifier: -

Note: re-importing already imported identifier: *

Note: re-importing already imported identifier: /
......

Best Regards!
