A carrot measures 100mm long and needs to be sliced into 100 1mm thick slices.


What is the minimum number of cuts required to do so if you are allowed to cut multiple pieces (from a previous cut) during a single slice?

    I think you got it - I could prove the 8 cut, and find 2. I thought there might be a 7-cut, but I wasn't sure.

    I like your analysis of the prime factors. I think you can improve on the 3rd cut's efficiency by going 16 & 9 instead of 24 &1. 24 requires 5 cuts to get it down to 1, but 16 & 9 require 4 cuts. That would bring your solution down to 7
