Easy  text   text remove text length - 3    I subtracted 3 because the Remove function removes all items from that index to the end of the string which is text length  So if I subtract 3 then I get the string with 3 characters removed from it   You can generalize this to removing a characters from the end of the string  like this   text   text remove text length - a     So what I did was the same logic  The remove function removes all items from its inside to the end of the string which is the length of the text  So if I subtract a from the length of the string that will give me the string with a characters removed   So it doesn t just work for 3  it works for all positive integers  except if the length of the string is less than or equal to a  in that case it will return a negative number or 0
