Picture of Knex Calculator
This, as the title suggests, is a calculator made out of knex.  It is extremely easy to use and requires a small amount of parts.  It can add the numbers 1-9 to create instantaneous answers of 1-18.

Is there any way to bypass the Knex Track?

Maybe you could just use normal yellow pieces.
Thanks, I made it with just yellow pieces like you said and changed the 2nd step a little and it works fine. 5 stars
