Numbers and strings are two different data types in Angular. A number denotes a numeric value, but a string is a series of letters surrounded in single or double quotations. Arithmetic operations can be carried out on numbers, which can be either integers or floating-point values. Contrarily, strings can be concatenated using the + operator but cannot be utilized in mathematical calculations. In general, strings are used to represent textual data while numbers are used to represent data that needs numeric values for calculations and other purposes.
