# Working with Strings

As we learned earlier, mathematical operations can not be performed on **strings**. If we try performing a mathematical operation on a string, we will get an error. The exception is, (+) can be used to merge the strings together. String concatenation or (*) could be used to repeat the string. But, this operation requires a string and an **integer** while working with strings.

No other mathematical operation is possible with the strings. If we try to perform such an operation, we will encounter another kind of error, **TypeError**, where it conveys that the operation is not possible between a string and another string.
