Introduction: 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.

Step 1: Body


Step 2: Processors


Step 3: Processor Track


Step 4: Display, Installing the Mobile Processor, and Building the Addition Wand


Step 5: How Do I Use It?

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
