Variables

Declaring variables

Declare a variable with the equals symbol =.

discount = 10%                         | 10%
cost =  200€                           | €200
cost - discount                        | €180

A variable can be a single word or an entire phrase (i.e. red apples = 10).

Redefining variables

A variable can be redefined by giving it a new value.

The most recently defined value will be used on subsequent lines.

amount = 50€                           | €50
amount x 2                             | €100
amount = 20€                           | €20
amount x 2                             | €40
