Arithmetic Operators

Arithmetic operators are needed to perform operations on different types of data. There are 2 basic types of arithmetic operators:

• Binary operators require two operands, such as x + y or a * b
• Unary operators require only one operand, such as -x or +x

Binary arithmetic operators

• Addition +
• Subtraction -
• Multiplication *
• Division /
• Remainder %
• Exponentiation **

Unary arithmetic operators

• The unary plus operator indicates a positive value. It's an optional operator if you only work with numbers
  • e.g. console.log(+7)
• The unary minus operator makes a value or an expression negative
  • e.g. console.log(-(100 + 5))
