Swift: Arithmetic Operators

Arithmetic Operators in Swift:

Let’s use arithmetic operators in Swift to calculate things now that we’ve specified variables.

Some of the basic arithmetic operators are as follows:

• + addition
• * multiplication
• - subtraction
• % modulo (divides and gives the remainder)
• / division

Consider the following example:

var points = 0;
// points are 0
 
points = 4 + 6;
// it is now 10
 
points = points - 2;
// it is now 8
 
points = 3 * 2;
// it is now 6
 
points = 8 / 4;
// and now 2
 
points = 5 % 2;
// and now 1

Note: Parentheses can be used to specify the order of operations. For example, in points = 3*(2 + 1), the parentheses make the points equal to 3*3 rather than 6 + 1.
