# Hi Mr.p
#--How to run--#
#1. Download then use steps per platform
#Linux: with bash, within working dir ./calculate.sh, make sure to allow exc
#Mac: Should work but minor difrents in corutilities may cause some dif, not sure if 'bc' works on mac so floating point calculations may fail
#Windows: Install linux subsystem then use linux instructions
