The most basic operation on strings is concatenation , connecting two strings to form a longer string whose length is the sum of the lengths of those two strings : abcde is the concatenation of ab with cde , in symbols abcde = ab ^ cde . Strings, and concatenation of strings can be treated as an algebraic system with some properties resembling those of the addition of integers; in modern mathematics, this system is called a free monoid.
