@@someone.-gi7zr Thank you! I am using cross-multiplication for the harder problems but for some problems I am looking for things that would make it easier (for example if I was doing 78x49 I would do 78x50-78) . Typically the cross multiplication problems are the ones that have taken me the longest.
