1. Arithmetic Operators

Swift supports the four standard arithmetic operators for all number types:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division ( / )
• Remainder ( % )

note: swift cannot add two different data types.

a simple example

let num1 = 3
let num2 = 12

let sum = num1 + num2
print(sum)
